FAQs about Frontier Airlines Flights from SEA to GDL

Flying Tips & Tricks How do I find my flight number?
  • Your travel 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 typically a couple of letters then a digit. Following that are several other numerals — your flight number.
How early can you check bags for a flight?
  • Check-in times differ between airlines. However, with international flights you can typically drop your baggage three hours before departure. We suggest getting to the airport with plenty of time to spare as check-in closes around an hour before departure. If you're traveling on a domestic flight, check-in and baggage drop open two hours prior to departure and close 45 minutes before takeoff.
