Flying Tips & Tricks How do I find my flight number?
  • The number is in your travel itinerary, which you'll receive upon confirmation of your booking. If you don't know what to look for, keep your eye out for a code containing numbers and letters. The first couple of letters and single digit are the IATA airline code, which indicates the name of your airline. This part is followed by one, two, three or four digits — your flight number.
How early can you check bags for a flight?
  • To have plenty of time to drop your baggage, clear security and customs and arrive at the correct boarding gate, get to the airport around three hours before an international flight. For a domestic flight, it's two hours. Even if you've already selected your seat and received your boarding pass online, it's worth bearing in mind that there are closing times for luggage check-in. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can vary between airlines, so it's a good idea to check these details well ahead of your flight.
