Our tips before you book

One ticket or several?

On a single ticket, the airline rebooks you if a flight is delayed. Flight Itinerary's « One ticket » filter keeps only combinations sold together.

Check the days of operation

Some routes don't fly every day, or only in certain seasons: each leg's calendar shows the days with flights.

Compare with round-the-world fares

when the alliances offer them: depending on the number of stops, they can be cheaper.
