Flying Tips & Tricks How do I find my flight number?
  • You'll find a code written in your itinerary, which will be sent to you when you've finished your booking. Just keep your eyes peeled for the IATA airline code (which consists of a couple of letters and a digit) followed by one to four digits — your flight number.
How early can you check bags for a flight?
  • To have enough time to drop your baggage, clear customs and security and find your boarding gate, head to the airport approximately three hours before an international flight. For a domestic flight, it's two hours. Even if you've already selected your seat and downloaded your boarding pass at home, it's worth noting that there are closing times for luggage drop. It's an hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can vary between airlines, so check these details ahead of time.
