How Early Should I Arrive at the Airport?
The real answer depends on your airport, airline, whether you have TSA PreCheck, and if you're checking bags. Here's a practical breakdown.
The general rule
The standard advice you'll hear from every airline is:
- Domestic flights: Arrive 2 hours before departure
- International flights: Arrive 3 hours before departure
But this is a one-size-fits-all guideline that doesn't account for your specific situation. Some travelers can safely arrive 90 minutes early, while others need the full 3 hours.
What actually determines how early you need to arrive
Your arrival time depends on four things that stack on top of each other:
| Factor | Typical time | Varies by |
|---|---|---|
| Drive to airport | 15–90 min | Distance, traffic, time of day |
| Bag drop | 0–60 min | Domestic (45 min) vs. international (60 min) |
| TSA security | 5–45 min | Airport, time of day, PreCheck status |
| Gate buffer | 30–45 min | Domestic (30 min) vs. international (45 min) |
Add these up and you get your real arrival time — which might be more or less than the standard "2 hours early" advice.
When airlines actually start boarding
Boarding doesn't start at departure time — it starts well before. If you're not at the gate when boarding begins, you risk losing your seat (or at minimum, your overhead bin space).
| Airline | Boarding starts | Gate closes |
|---|---|---|
| American Airlines | 40 min before departure | 15 min before |
| Delta | 35–40 min before | 15 min before |
| United | 30–35 min before | 15 min before |
| Southwest | 30 min before | 10 min before |
| JetBlue | 30 min before | 20 min before |
| International (widebody) | 50–60 min before | 15–20 min before |
TSA PreCheck makes the biggest difference
Across the 12 busiest US airports, PreCheck lanes average 60–70% shorter wait times than standard lanes. At some airports the difference is dramatic:
| Airport | Standard lane | PreCheck | You save |
|---|---|---|---|
| JFK | ~28 min | ~10 min | 18 min |
| MCO (Orlando) | ~26 min | ~9 min | 17 min |
| MIA | ~24 min | ~8 min | 16 min |
| LAX | ~22 min | ~8 min | 14 min |
At $78 for 5 years, PreCheck pays for itself in time savings after just a few flights.
Check live wait times at your airport
Rather than guessing, check the current TSA wait time at your departure airport before you leave:

- Domestic, PreCheck, no bags: 75–90 minutes early is usually comfortable
- Domestic, standard lane, checking bags: 2–2.5 hours early
- International, checking bags: 3 hours early (some airlines require this)
- Peak travel days (Friday PM, Sunday PM, holidays): Add 30 minutes to all of the above
- Unfamiliar airport: Add 15–20 minutes for navigation and wayfinding
The bottom line
The "2 hours early" rule is a decent starting point, but the real answer is personal. Your drive time, your airport, your PreCheck status, and whether you're checking bags all change the math.
