Flying Tips & Tricks How do I find my flight number?
  • Your itinerary contains essential information for your forthcoming adventure, including your flight number. Unsure what it looks like? There's an IATA airline code at the beginning, which is generally a couple of letters then a single digit. Following that are several other numerals — your flight number.
How early can you check bags for a flight?
  • To have enough time to drop your luggage, clear customs and find the correct boarding gate, get to 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 check-in. It's an hour before departure for international flights, and 45 minutes if you're flying domestically. Of course, times can vary between airlines, so it's a good idea to check these details ahead of time.
