Frequently asked questions
If I book a code-share ticket, which airline am I actually flying on?
You are flying on the operating airline's aircraft, with the operating airline's crew, under the operating airline's safety regulations. The marketing airline is the one whose code and flight number appears on your ticket. Both pieces of information are typically shown clearly at booking — for example, IndiGo flight 6E1234 operated by Turkish Airlines flight TK0123. Check the booking confirmation to see both. Your in-flight experience is determined by the operating carrier.
Can I credit miles to my favourite frequent flyer programme on a code-share?
Usually yes, with constraints. Code-share bookings allow credit to either the marketing carrier's programme or the operating carrier's programme, generally not both. You choose at booking. The earning rate may vary by booking class and partner — some discount fare buckets earn lower miles when credited to a partner programme. Check the specific earning rate before choosing. For tier renewal or status flying, the choice can be material.
Is the baggage allowance on a code-share ticket different from a regular ticket?
Yes, often. Most code-shares apply the operating carrier's baggage rules for each segment. If your ticket has segments on different carriers, each segment may have different baggage allowance. For most India-origin international tickets in economy, the allowance is typically 30 kg total — but premium cabins and specific partner carriers may differ. Confirm the baggage allowance at booking and again at airport check-in for each segment.
What happens if a code-share flight is cancelled or significantly delayed?
The marketing carrier (the airline you booked through) is responsible for customer service and rebooking. The operating carrier handles operational alternatives like aircraft swaps. You should contact the marketing carrier first for cancellations and rebooking, but at the airport speak to whichever carrier's customer service is available. The compensation rules depend on the jurisdiction — EU EC261 applies to flights operated by EU airlines or departing from EU airports regardless of code.
Do I get lounge access on a code-share flight if I have status with the marketing airline?
Generally yes, if both airlines are in the same alliance. Air India Gold status (Star Alliance Gold equivalent) gets lounge access at Star Alliance airports for international flights. The same applies to IndiGo 6E Elite for partner lounges where IndiGo has arrangements. For airline-specific partnerships outside an alliance, lounge access depends on the specific partnership terms. Check the lounge access rules before relying on it for an unfamiliar code-share routing.
Is the IndiGo-Turkish code-share actually cheaper than booking Air India direct to London?
Often yes, by 10,000 to 20,000 rupees in economy. The IndiGo-Turkish BOM-IST-LHR routing typically clears at 42,000 to 58,000 rupees in shoulder season, versus 55,000 to 75,000 for an Air India direct BOM-LHR. The trade-off is a transit at Istanbul, which adds 3 to 4 hours of total journey time. For price-sensitive travellers it is worth the trade-off; for time-sensitive travellers the direct flight remains compelling.
Can I select my seat in advance on a code-share booking?
Usually yes, but the process can be friction-prone. The marketing carrier's system may or may not allow direct seat selection on the operating carrier's metal. The smoother approach is often to use the operating carrier's website with your reservation code (locator) and select seats directly. For premium cabin bookings, advance seat selection is more reliably supported. For deep-discount economy, some code-shares restrict advance seat selection until check-in.
Does Air India have code-shares for all Star Alliance destinations or only some?
Air India has code-share arrangements with most major Star Alliance partners but the depth varies. The strongest code-share arrangements are with Singapore Airlines (deep SIN connection feed), Lufthansa (Europe feed), United (US feed) and ANA (Japan). Code-shares with smaller Star Alliance carriers like Aegean or Brussels Airlines may be more limited. Check specific routings at booking on airindia.com — the system will show which code-shares are available for your specific city pair.
