Common Mistakes to Avoid
⚠️
Only counting flight time
A '5-hour flight' is really 8-9 hours door-to-door when you include airport time. Always plan realistically.
⚠️
Underestimating international arrival time
International arrivals require customs and immigration, which can add 1-2 hours. Add more buffer.
Frequently Asked Questions
How early to arrive at the airport? ▾
Domestic: 2 hours. International: 3 hours. During holidays: add 30-60 minutes. TSA PreCheck or CLEAR can reduce domestic security to 15-20 minutes.
What is a reasonable layover time? ▾
Domestic connection: 45-60 min minimum. International: 2+ hours. If connecting from international to domestic: 2.5+ hours for customs.
Time zone effect on arrival time? ▾
Flying west gains hours; flying east loses hours. NYC to LA: depart 8 AM, 5.5 hr flight = arrive 1:30 PM (LA time, but only 4.5 hrs later in body time).
