When taking flights, are you hesitant about how early to get to the airport? Wanna avoid missing your flight and boring time spent in the overpriced cafe at the airport? This guide is all you need—whether you’re taking a domestic or international flight, we offer pro tips and specific cut-off times for your smooth travel.
How Early to Get to the Airport for Domestic Flights?
Are you a gate sprinter or an early bird? Arrive too late, you risk missing your flight; arrive too early, you have to bear the airport noise. For domestic travel within the U.S., arriving 2 hours early before departure is enough for most travelers, including check-in, security, and some unpredictable cases.
Standard Recommended Time
By arriving 2 hours early, you’re able to:
- Check in 30 minutes before departure
- Tag your checked bags (if needed)
- Clear security for 15–30 minutes
- Walk to your gate without sprinting
Notes: Security checks can cause long lines. Especially at major hubs like Hartsfield-Jackson or O’Hare, everyone needs to take off their jackets and boots, as well as take their electronics out of bags.
Checking Bags vs. Carry-On Only
Your luggage strategy impacts your timeline:
- Checked bags: Usually, the check-in counter line can add 30+ minutes, and baggage cutoff times are typically 45 minutes pre-departure. If you miss the cut-off time, some airlines like Southwest Airlines will tag a Late-Check-In Tag.
- Carry-on only: In this case, you can pass the check-in counter and head straight to the security check. Slash your arrival time by 10 minutes with TSA PreCheck.

Busy Airports vs. Regional Airports
Rules may be different by airports:
- Major hubs (JFK, LAX, MIA): Stick to the full two-hour window. Security lines peak between 5–8 AM and 4–7 PM.
- Regional airports (BNA, PDX, AUS): Usually manageable in 90 minutes, especially during off-peak hours.
Pro tip: Holiday seasons such as Christmas and Thanksgiving can result in longer lines, so if you have a holiday travel plan, remember to arrive early, no matter what kind of airport.

Airline-Specific Requirements
Carriers have unique international policies:
- Emirates: Requires check-in at least 90 mins before departure
- Lufthansa: Arrive 3 hours before for long-haul routes
- Delta: Baggage must be checked 45 mins before departure.
Layovers and Connecting Flights
Multi-leg journeys demand strategic planning:
- Domestic-to-international connections may require rechecking bags
- Separate tickets mean you’ll need to claim and recheck luggage
- Minimum connection times vary (e.g., 60 mins at JFK vs. 2-3 hrs at LAX)

Factors That Affect Arrival Time
Peak Travel Seasons & Holidays
Nexer underestimated the holiday season and peak hours:
- Holiday periods: Expect 60+ minutes added to standard times
- Summer weekends: Longer security waits at the airport
- Early mornings (5–7 AM): Business travelers can cause rushes at the checkpoint.
Airport Size and Layout
The size of the airport also matters when planning:
- Dallas/Fort Worth: DFW has one of the longest airport walk in the U.S..
- Denver: Denver’s mile-long concourse requires ~2000 steps before boarding.
- Austin/Texas: Smaller airports let you walk to the gate in a comparatively short distance.
Special Needs (Wheelchairs, Minors, Pets)
- Wheelchair users: Request assistance and check carry-on restrictions in advance
- Pet owners: Save extra time for health certificate verification
- Unaccompanied minors: Book the service 48 hrs before and arrive early for extra paperwork.
Ride-Sharing vs. Parking
Your arrival method can also impact timelines:
- Uber/Lyft: Consider peak hours; traffic jams can cause you to miss your flight.
- Shuttle bus: Check the frequency with the timetable (always available on airports’ official websites)
- Private car: Arrive early for parking and walking to your terminal.
