What airline is F9?
The IATA code for Frontier Airlines is F9. All airlines are designated an IATA code by the International Air Transport Association. It's used for many purposes, such as tickets, tariffs, communications and timetables.
How do I find my flight number?
You will receive a travel itinerary when you complete your booking. In this document you'll see your flight number. The first one to two letters and single figure indicate your airline name (these are called IATA airline codes). This is followed by one to four digits --- the flight number.
How early can you check bags for a flight?
To have ample time to drop your baggage, clear security and customs and find the correct 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 been allocated your seat and downloaded your boarding pass at home, it's worth bearing in mind that there are closing times for baggage check-in. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can vary between airlines, so it pays to check these details ahead of your flight.
