Flying Tips & Tricks How do I find my flight number?
  • You'll find a code written in your travel itinerary, which will be sent to you when you've completed your booking. Just keep your eyes peeled for the IATA airline code (which is one to two letters and a single digit) followed by one to four digits — your flight number.
How early can you check bags for a flight?
  • To have plenty of time to drop your bags, clear customs and security and arrive at the correct boarding gate, arrive at the airport three hours before an international flight. If you're traveling domestically, show up around two hours before. 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 one hour before departure for international flights, and 45 minutes if you're flying domestically. Of course, times can vary between airlines, so it's wise to check these details ahead of your flight.
