Flying Tips & TricksHow do I find my flight number?
  • Your flight code will be on your itinerary, which will be sent to your inbox once your booking has been locked in. It's a good idea to keep this near at hand in case you need to make any changes to your ticket.
How early can you check bags for a flight?
  • To have ample time to drop your baggage, clear customs and show up at the correct boarding gate, head to the airport approximately three hours before an international flight. For a domestic flight, show up around two hours before. Even if you've already picked 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 differ between airlines, so check these details when you book.
