An <strong>interline<\/strong> agreement lets two airlines issue single tickets across each other&#8217;s separate flights and transfer your baggage.

You&#8217;ll connect through a hub, and your journey will likely involve two different airlines.<\/p>\n<p>How those two airlines cooperate determines:<\/p>\n<ul>\n<li>Whether your bags go straight to your final destination or you have to collect and re-check them<\/li>\n<li>Whether you&#8217;re protected if you miss your connection due to a delay<\/li>\n<li>Whether you can earn frequent flyer miles on the whole journey<\/li>\n<li>Who is responsible if something goes wrong<\/li>\n<\/ul>\n<p>The two main types of airline cooperation are <strong>codeshare<\/strong> and <strong>interline<\/strong>. Here&#8217;s how each works, with real examples for Indian travellers.<\/p>\n<h2>Codeshare Flights: One Flight, Two (or More) Flight Numbers<\/h2>\n<p>A codeshare is a specific arrangement where two airlines sell seats on the <strong>same physical flight<\/strong>. One airline <strong>operates<\/strong> the flight \u2014 providing the aircraft, crew, catering, and ground handling. The other airline <strong>markets<\/strong> the flight \u2014 selling it under its own flight number and brand.<\/p>\n<h3>How It Works \u2014 A Real Example<\/h3>\n<p>You search for Delhi to London on <a href=\"https:\/\/happyfares.in\" style=\"color:#0066cc;\" target=\"_blank\" rel=\"noopener\">HappyFares<\/a>.

United is the &#8220;marketing carrier&#8221; \u2014 it sells the seat. Air India is the &#8220;operating carrier&#8221; \u2014 it flies the plane.<\/p>\n<h3>Why Airlines Do This<\/h3>\n<ul>\n<li><strong>For the marketing carrier:<\/strong> United can offer &#8220;Delhi to London&#8221; in its system without actually flying that route. A United customer in Chicago can book a through-itinerary Chicago \u2192 London \u2192 Delhi, all under United flight numbers, even though the London\u2013Delhi leg is flown by Air India.<\/li>\n<li><strong>For the operating carrier:<\/strong> Air India fills more seats on its Delhi\u2013London flight because United is also selling tickets for it.<\/li>\n<li><strong>For you:<\/strong> More booking options.

Unlike codeshare, interline does <strong>not<\/strong> involve sharing the same flight. Each airline operates its own separate flights. The cooperation is about <strong>ticketing and baggage<\/strong>:<\/p>\n<ol>\n<li>Both airlines can be included on a <strong>single ticket<\/strong> (one PNR)<\/li>\n<li>Your <strong>baggage transfers<\/strong> between the two carriers without you needing to collect and re-check<\/li>\n<li>If your first flight is delayed and you <strong>miss your connection<\/strong>, the airlines coordinate to rebook you<\/li>\n<\/ol>\n<h3>How Interline Works \u2014 A Real Example<\/h3>\n<p>You want to fly from Kolkata to Rome. No airline flies this route direct. With an interline agreement between IndiGo and a European carrier:<\/p>\n<ul>\n<li><strong>Leg 1:<\/strong> IndiGo 6E 123 \u2014 Kolkata to Delhi (IndiGo aircraft, IndiGo crew)<\/li>\n<li><strong>Leg 2:<\/strong> Turkish Airlines TK 717 \u2014 Delhi to Istanbul to Rome (Turkish aircraft, Turkish crew)<\/li>\n<\/ul>\n<p>Because IndiGo and Turkish Airlines have an interline agreement, and you booked through an OTA like HappyFares that issues interline tickets, you get:<\/p>\n<ul>\n<li>A single booking reference (PNR) for the entire journey<\/li>\n<li>Baggage checked through from Kolkata to Rome<\/li>\n<li>If IndiGo&#8217;s Kolkata flight is delayed and you miss the Turkish connection in Delhi, the airlines coordinate to put you on the next available flight<\/li>\n<\/ul>\n<h3>When Interline Protection Does NOT Apply<\/h3>\n<p>If you book <strong>two separate tickets<\/strong> \u2014 one for IndiGo and one for Turkish Airlines \u2014 you get <strong>none<\/strong> of these protections:<\/p>\n<ul>\n<li>Your baggage will NOT transfer automatically. You must collect your bags in Delhi, exit security, re-check-in with Turkish Airlines, and go through security again.<\/li>\n<li>If you miss your Turkish Airlines connection because IndiGo was late, Turkish Airlines has no obligation to rebook you. You&#8217;re treated as a no-show and may lose that ticket entirely.<\/li>\n<\/ul>\n<p>This is called a <strong>&#8220;self-connection&#8221;<\/strong> \u2014 and it carries real financial risk. You&#8217;re essentially on your own between the two flights.<\/p>\n<div style=\"background:#fff3e0;border-left:4px solid #ff9800;padding:16px 20px;margin:20px 0;border-radius:4px;\">\n  <strong>This is why booking through HappyFares matters.<\/strong> When you search for a multi-leg international itinerary on HappyFares, the system checks interline and codeshare availability automatically. If your itinerary can be issued as a single interline ticket, it will be \u2014 giving you baggage transfer and connection protection without you having to think about it.\n<\/div>\n<h3>Indian Airlines \u2014 Interline Partners<\/h3>\n<p><strong>Air India<\/strong> has interline partnerships with 109 carriers, offering connections to 800+ global destinations. Recent additions include airBaltic, Bulgaria Air, Cyprus Airways, Uzbekistan Airways, and Scoot (60+ destinations across Southeast Asia, North Asia, and Australia).<\/p>\n<p><strong>IndiGo<\/strong> has focused more on codeshare agreements than traditional interline, but does have virtual interline arrangements \u2014 including one with Jetstar through the Dohop-powered Jetstar Connect platform.<\/p>\n<h2>Codeshare vs Interline: The Complete Comparison<\/h2>\n<table style=\"width:100%;border-collapse:collapse;margin:16px 0;\">\n<tr style=\"background:#f5f5f5;\">\n<th style=\"padding:10px;text-align:left;border:1px solid #ddd;\">Feature<\/th>\n<th style=\"padding:10px;text-align:left;border:1px solid #ddd;\">Codeshare<\/th>\n<th style=\"padding:10px;text-align:left;border:1px solid #ddd;\">Interline<\/th>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Same physical flight?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes \u2014 two flight numbers, one aircraft<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">No \u2014 each airline flies its own plane<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Single ticket?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes (when booked correctly through OTA or airline)<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Baggage transfer?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes \u2014 automatic<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes on single ticket; depends on agreement specifics<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Connection protection?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes \u2014 airlines coordinate rebooking<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Yes on single ticket; none on separate tickets<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Miles earning?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Usually earn with marketing carrier<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Earn separately on each airline&#8217;s segment<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>In-flight service?<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Operating carrier&#8217;s service<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Each airline provides its own service<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Level of integration<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">High \u2014 airlines share the same flight<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Moderate \u2014 cooperation on ticketing and bags<\/td>\n<\/tr>\n<tr style=\"background:#f9f9f9;\">\n<td style=\"padding:10px;border:1px solid #ddd;\"><strong>Number of partnerships<\/strong><\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Fewer, more strategic<\/td>\n<td style=\"padding:10px;border:1px solid #ddd;\">Broader \u2014 airlines may have 100+ interline partners<\/td>\n<\/tr>\n<\/table>\n<h2>Practical Tips for Booking Codeshare and Interline Flights<\/h2>\n<ol>\n<li><strong>Always check the &#8220;operated by&#8221; line.<\/strong> Your booking confirmation will say &#8220;Marketing Carrier: United | Operated by: Air India.&#8221; The operated-by airline determines your seat, meal, and service quality.<\/li>\n<li><strong>Book through a single ticket \u2014 always.<\/strong> This is the most important rule. A single ticket (one PNR) gives you baggage transfer, connection protection, and a single point of contact if things go wrong. When you book connecting flights on HappyFares, multi-airline itineraries are issued as single tickets wherever codeshare or interline agreements exist.<\/li>\n<li><strong>Check baggage rules for both carriers.<\/strong> Flying IndiGo domestic + Turkish Airlines international on a codeshare ticket? Your checked baggage allowance follows the ticket rules, but cabin baggage dimensions may differ between the two carriers. IndiGo allows 7 kg cabin bag; Turkish allows 8 kg. Pack to the stricter limit.<\/li>\n<li><strong>For frequent flyer miles \u2014 check before you book.<\/strong> Not all codeshare fares earn the same miles. Deeply discounted tickets sometimes earn fewer (or zero) miles. Check the earning chart for your specific loyalty programme and fare class before booking.<\/li>\n<li><strong>Allow sufficient connection time.<\/strong> Even with codeshare and interline protection, tight connections are risky \u2014 especially at busy airports like Delhi T3 or Mumbai T2. Allow at least 2\u20133 hours for international connections and 90 minutes for domestic-to-international at the same airport.<\/li>\n<li><strong>Know who to call when things go wrong.<\/strong> On a codeshare, the operating carrier handles ground disruptions. On an interline, contact the airline operating the delayed leg.

One airline operates the aircraft (operating carrier), the other sells seats under its own code (marketing carrier). You board the operating carrier&#8217;s plane no matter which airline you booked through.<\/p>\n<h3>What is the difference between codeshare and interline?<\/h3>\n<p>In a codeshare, two airlines share the same flight \u2014 one operates, one markets it. In interline, each airline operates its own separate flight, but they cooperate on ticketing and baggage so passengers can book both on a single ticket and have bags transferred automatically. Codeshare is tighter integration; interline is simpler cooperation.<\/p>\n<h3>How do I know if my flight is a codeshare?<\/h3>\n<p>Look for the phrase &#8220;operated by&#8221; on your booking confirmation or e-ticket. If the operating airline is different from the one you booked with, it&#8217;s a codeshare. For example, &#8220;UA 8285 operated by Air India&#8221; means you booked through United but will fly on an Air India plane.<\/p>\n<h3>Does my baggage transfer on interline flights?<\/h3>\n<p>If your entire journey is on a single ticket (one PNR) issued under an interline agreement, your bags are typically checked through to your final destination. If you booked two separate tickets, you must collect and re-check your bags yourself at the connecting airport.<\/p>\n<h3>Can I earn miles on a codeshare flight?<\/h3>\n<p>Usually yes. You can earn frequent flyer miles with the marketing carrier&#8217;s programme or (if both airlines are in the same alliance) with any alliance member&#8217;s programme. The number of miles depends on the fare class \u2014 some cheap codeshare fares earn reduced or zero miles.<\/p>\n<h3>What happens if my codeshare flight is cancelled?<\/h3>\n<p>The operating carrier manages rebooking and alternate arrangements at the airport. Your refund or compensation claim goes through whoever sold you the ticket. If you booked through HappyFares, contact <a href=\"https:\/\/help.happyfares.in\" style=\"color:#0066cc;\" target=\"_blank\" rel=\"noopener\">help.happyfares.in<\/a> \u2014 our team handles coordination with both airlines.<\/p>\n<h3>Is it safer to book codeshare or interline?<\/h3>\n<p>Both are safe and offer protection when booked on a single ticket. The real risk is booking <strong>separate tickets<\/strong> for connecting flights \u2014 that gives you zero protection. Whether your connection is codeshare or interline, what matters most is that it&#8217;s on one ticket (one PNR).<\/p>\n<h3>Which Indian airlines have the most codeshare partners?<\/h3>\n<p>Air India has the most codeshare partners among Indian carriers, thanks to its Star Alliance membership \u2014 including Lufthansa, United, Singapore Airlines, ANA, Swiss, and Air Canada. IndiGo is a close second, with codeshare agreements covering Turkish Airlines, American Airlines, Qantas, British Airways, KLM, Air France, Qatar Airways, Japan Airlines, Delta, Virgin Atlantic, and Malaysia Airlines.<\/p>\n<div style=\"background:#e6f4ea;border:1px solid #34a853;padding:16px 20px;border-radius:6px;margin:24px 0;\">\n  <strong>Book Smart on HappyFares<\/strong><br \/>\n  When you search connecting international flights on HappyFares, codeshare and interline availability is checked automatically.
