To save time at the airport, Frontier Airlines LAS Terminal encourages travelers to check in online starting 24 hours before their flight. You can use the Frontier website or mobile app to check in, choose your seat, purchase baggage, and get your boarding pass electronically. If you need to check in at the airport, Terminal 3 has self-service kiosks that allow you to quickly print boarding passes and baggage tags. There are also staffed counters where you can get assistance with special needs, ticketing, or baggage issues.
