Online Check-In: What Is It?

Before you arrive at the airport, you can conveniently confirm your flight and get your boarding pass by checking in online. Travelers can check in online 24 to 48 hours before departure by visiting the airline's website or mobile app, frequently through travel portals like Trip.com, rather than standing in large lineups at the check-in desk.

Checking in online is simple with Trip.com. When your airline's check-in window opens, you will receive instructions and reminders after making your reservation. From there, you can:

  • Enter your ticket number or booking reference.
  • Choose the seat of your choice.
  • Select whether to print, email, or use a mobile device for your boarding pass.
  • Spend less time at the airport, particularly if you are only bringing hand luggage.
