BUF TSA wait times by hour

Quick answer

Allow up to 30 minutes for security at BUF at its busiest (5–6 AM) and about 15 in the 7–9 PM lull, or 10 and 5 with PreCheck. TSA doesn't publish wait times by airport, so these are planning allowances from its hourly counts of people screened, not live waits. Get to BUF about 1 h 30 min before a domestic flight around 6:30 AM, or 1 h 15 min before one around 8:30 PM, with just a carry-on. Add about 20 minutes to check a bag.

BUF security wait times by hour

People screened per hour across BUF's checkpoints, averaged over 7 weeks of TSA data (Sep 6 to Oct 24, 2026), and how long to allow for security in each hour. More people means longer lines, though TSA staffs up for the peaks, so read it as when lines build rather than exact waits.

Security at BUF is busiest 5–6 AM, when about 980 people go through every hour: 21.7 times as many as in the 7–9 PM lull.

Monday is the busiest day (about 9,200 people) and Wednesday the quietest (about 7,500). Screening at BUF picks up around 3 AM, lines build from about 4 AM and it winds down after 8 PM.

TSA reports its lines against 30 minutes: on the busy Fourth of July weekend in 2021, 99.7% of travelers in standard lanes waited less than that. So at BUF's busiest hours we plan for 30 minutes in the standard lane and 10 with PreCheck, and less when it's quieter.

These aren't live waits. For today's line, check Buffalo Niagara International Airport's official site: many airports post live checkpoint waits.

How early to get to BUF

How long before departure to reach the airport if you're dropped off at the terminal. Flights around 6:30 AM hit security in its busiest hour; flights around 8:30 PM in a quieter stretch.

Your tripFlights around 6:30 AMAround 8:30 PM
Domestic, carry-on only1 h 30 min1 h 15 min
Domestic, checking a bag1 h 50 min1 h 25 min
Domestic, carry-on, PreCheck or CLEAR1 h 10 min1 h 5 min

Parking adds 15 to 25 minutes and returning a rental car about 30; the calculator above adds them for you. Most U.S. airlines close bag drop 45 minutes before domestic departures and 60 before international ones, and on holiday weekends we'd allow another 15 to 25 minutes. How we work these out

BUF security checkpoints

BUF screens departing travelers at one main checkpoint.

Terminals: One terminal with east and west gate areas. One terminal with 24 gates on either side of a central checkpoint.

Getting through BUF security faster

  • Fly Wednesday, or at a time that reaches security in the 7–9 PM lull, if you can: BUF's checkpoints see about 50 people an hour then, against 980 at the peak.
  • TSA PreCheck or CLEAR: in TSA's 2021 holiday-weekend figures 99% of PreCheck travelers waited under 5 minutes. In our plan it saves about 20 minutes at BUF's busiest hours.
  • Checking a bag? The bag drop lines peak at the same hours as security, so add about 20 minutes then, and get there before your airline closes bag drop (usually 45 minutes before a domestic flight).
  • On the first flights of the day, expect a line as soon as screening starts: lines at BUF build from about 4 AM.

BUF TSA wait times FAQ

About 1 h 30 min before departure with just a carry-on if your flight leaves around 6:30 AM, when security at BUF is busiest, or 1 h 15 min around 8:30 PM. Checking a bag, allow 1 h 50 min at the busiest times. That's for being dropped off at the terminal; add 15 to 25 minutes to park.
