We are going to Las Vegas and have a 6:30PM return flight on Frontier (returning to US city). We would like to rent a car at noonish and explore the desert for a while. So can we check in our bags that early and what time do we need to be back at the airport?
According to Frontier Baggage Requirements:
WHAT TIME CAN BAGS BE CHECKED?
You can check your bags up to two hours prior to your departure, so you have plenty of time to relax at the airport. Just be sure to check the Airport & Terminal info at the airport you’re flying out of, as airports in smaller cities can have different policies.
*Remember: For domestic flights you must be checked in with your baggage checked no later than 45 minutes before you departure and 60 minutes before departure for international flights.
For six hours before your flight, you will have to either take your bags with you, or store them in a bag locker at the airport.
