Yes, although to be on the same ticket, the airlines must have an interline ticketing agreement with each other. If you use a travel agent, you can also have connecting flights from different airlines on separate tickets but in the same itinerary (same record, same PNR).
Do I get both boarding passes in a connecting flight?
Yes. You'll probably get all boarding passes at once when you check in for your first flight, whether you check in online, on your smartphone, or at the airport. For some international itineraries though, the airline will direct you to get your second boarding pass on your layover.
Are connecting flights on one ticket?
What happens if you miss one of your connecting flights?
If your itinerary was purchased as one ticket (as in: you have only one itinerary and one confirmation number), and the connection time was too short and you miss the second (or third) flight, you can rest easy, no matter what happens. The airline will simply put you onto the next available flight, free of charge.
What happens if I decide not to take my connecting flight?
Generally speaking, whenever you book a flight on any airline, it treats the trip as one, complete itinerary. If you then don't show up for any portion of it, the rest of the unflown flights will be cancelled and then subject to a change fee and possible fare difference if you then try to rebook.
Can I check-in online for connecting flights?
Online check-in for both flights at once is usually available 24 hours before the scheduled deparature. However, each airline sets their own check-in time, therefore we ask you consult the information available on each carrier's website.
