Yes, yes. Our airport customer service agents are happy to check your luggage to your final destination, provided your flights comply with our minimum time rules. Please allow yourself extra time for check-in, through security and arrive in time for boarding at the boarding gate. And for the last time, I checked in February 2016, Singapore Airlines had no U.S. national airline that would give them luggage on 2 tickets…. even Star Alliance airlines. So, really double and triple answers here. In February, I had mixed responses. I even drove Cathay and booked United because I was told they were going to pass the bags… But when I arrived at the airport, that was not the case. I came to Chicago ORD and I couldn`t get my bags on time…. He ran to the International and had to choose to fly without luggage or miss the flight. I asked Cathay if they could get the bags and send them on the next flight, and she said no.
The answer depends on your ticket. If all your flights with several airlines are on the same ticket, your luggage will be checked to your final destination. If you fly different airlines with different tickets, you must pick up your luggage at connecting airports and check in for your next flight. An Interline agreement allows a passenger to easily access a destination with different airlines, change planes and have checked baggage on the last baggage allowance during landing. In this way, airlines can issue a single ticket on different airlines. It is also how airlines can issue you a ticket in case of delay or cancellation with another airline: the one with which they have an Interline agreement. For example, one of the last codeshares announced is between Lufthansa and Vistara. Lufthansa is heading to Delhi, but has no network inside India. Thanks to this codeshare, passengers from any Lufthansa destination can book in a number of new cities in India, including Ahmedabad, Bengaluru, Goa, Hyderabad, Kochi and Pune. This is an evolution of an earlier interconnection agreement between the two airlines, which implies a deeper relationship.
In the cases listed below, if more than one ticket is presented, Delta will continue to check the baggage from the original to the final destination. In all of these partnerships, the exact details will vary depending on the agreement reached.
