If I add another flight my to my trip, will I have more than one ticket?

When you add another flight to an itinerary, it's as if you are booking two separate tickets under one trip. That's the difference between building a multi-city route and separating it into different tickets.

Your goal is to plan a comfortable flight schedule and spend less money, so it's a good idea to run your search as both a multi-city option and individual tickets to find the best flights for you.
