Months ago, we booked seats on Delta in business class from LA to SIN, because we received a lot of things. We now book the rest of our inter-Asian trip. Has anyone had any luck lately to ensure that airlines with interline baggage contracts interline baggage if flights are not booked on the same ticket? Specifically, we travel to Malaysia from Siem Reap to SIN (arrival at 9 p.m.) and connect the next morning at 6:00 a.m. with our Delta flight to the United States. We hoped we would not be able to pick up the luggage and leave the airport and use the transit hotel. We booked Malays because they have an inter-line agreement with Delta. I know the Malay can, but is not obliged to check the luggage with another airline if the tickets were issued separately. And yes, I checked, Delta will only accept 3 hours in advance in the luggage of SIN. An interline flight is an agreement between airlines to coordinate passengers with an itinerary that uses multiple airlines without having to relocate or drop off their luggage during the stopover.
Codeshare agreements are airline flights on behalf of another airline using their flight code. For example, a ticket you bought from Finnair but British Airways operates with a British Airways aircraft. Even if a route needs several airlines, I would still try to find the version with the underlying flight number as the codeshare variant (if they can rent it the same way). Whenever there are flight problems, code-sharing issues are the worst because airlines like to send you to the other side to fix them. Most Interline agreements include a section on registration, which means that the customer only has to register once for the entire itinerary. This is usually the case for the airline that operates the first segment of the flight. However, if you are unsure, contact the airline to make sure you check in for the entire itinerary and with the right airline to avoid extra charges or missed flights. Have you read the question -- Risk of connecting flights on separate tickets. I would be more concerned about whether your baggage will be transferred If you establish international connections with other airlines within 12 (12) hours of your arrival in the connecting city, you can comply with the baggage and weight limits of the international airline, provided there is a ticket and baggage contract between Alaska Airlines and the other airline.
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. Some low-cost airlines, such as Southwest, did not have Interline agreements, which meant that their passengers had to pick up their luggage and go to the check-in desk to check their luggage again. As a general rule, even U.S. airlines that do not have a partnership with each other have an interconnection agreement. A few years ago Delta decided to disable an interline agreement with American, I think because they found that American more passengers on them during irregular operations than vice versa.
