A smooth airport day starts the day before. These steps work with almost any airline.
Check in online
Most airlines open online check-in 24 hours before departure; some open earlier. Use the airline's app or website with your confirmation code (also called a record locator or PNR). Checking in early can also help you get a better seat on fares that allow free seat selection at check-in.
How early to arrive
- US domestic flights: about 2 hours before departure is a safe guide; earlier at busy times.
- International flights: about 3 hours before departure.
- Bag-drop deadlines are strict, often 45 to 60 minutes before domestic departures and longer for international flights. Check your airline's exact cut-off.
Security
- Liquids in carry-on bags must be in containers of 3.4 oz (100 ml) or less, in one clear quart-size bag.
- Keep laptops and large electronics easy to reach unless you are in a lane that allows them to stay in the bag.
- Programmes such as TSA PreCheck and Global Entry can shorten queues; apply well before you travel.
On the day
- Check your flight status before you leave home.
- Have your ID or passport, boarding pass and any visas in one place.
- Charge your phone; mobile boarding passes need battery.
