Holiday travel

Memorial Day weekend flight delays

The long weekend ending on the last Monday of May, the unofficial start of summer travel.

Based on 2026 and earlier data. 2027 results expected around July 2027. Historical statistics, not a forecast and not live status.

Memorial Day weekend 2027 falls on Friday 28 May 2027 to Monday 31 May 2027. What follows is based on 2026 data and the years before it, back to 2023; figures for 2027 itself should arrive around July 2027, once the US DOT has published the months it covers.

The data backs up Memorial Day weekend's reputation: 2 of its last 3 years showed a measurable effect. Still, 2 years ran more punctually than normal, so the effect cuts both ways.

Of the 4 Memorial Day weekends on record here (2023, 2024, 2025 and 2026), 3 moved a headline figure past the test and 1 did not.

Patterns

What repeats from year to year

Between years the holiday swung by 12.6 points, from 72.0% on time in 2024 to 84.6% in 2023.

The busiest single day each year was Friday 26 May 2023 (19,696 flights), Friday 24 May 2024 (20,852 flights), Friday 23 May 2025 (20,826 flights) and Friday 22 May 2026 (21,005 flights).

Each year's weakest day: Friday 26 May 2023 (78.2%), Friday 24 May 2024 (68.2%), Monday 26 May 2025 (71.9%) and Friday 22 May 2026 (71.0%). The worst day moved around from year to year, which points to weather rather than to a fixed crunch in the holiday schedule.

The strongest day of the window across 2023, 2024, 2025 and 2026 was the Saturday, 80.3% on time on average, and the weakest the Friday at 74.9%. Memorial Day weekend lands on the same weekdays every year, so this is a pattern to plan around.

Early or late matters: 5am–8am departures averaged 89.4% on time across 2023, 2024, 2025 and 2026, 5pm–8pm departures 66.0%. That 23.4 points gap is bigger than the holiday effect itself.

2024 was the year for cancellations, 1.40% of scheduled flights and 5.46% at New York (LGA); the calmest was 2023 at 0.46%.

Airports and airlines

Who handles Memorial Day weekend best

Averaged across 2023, 2024, 2025 and 2026, the airports that handled the holiday best against their own normal weeks were Las Vegas (LAS, +5.7), Austin (AUS, +4.9) and Miami (MIA, +4.9); the ones that struggled most were Atlanta (ATL, −6.5), Chicago (ORD, −4.0) and New York (LGA, −3.6).

Each year one airport took the biggest hit against its own normal weeks: Denver (DEN, −2.7 points) in 2023, Atlanta (ATL, −22.1 points) in 2024, Denver (DEN, −15.0 points) in 2025 and Atlanta (ATL, −20.5 points) in 2026.

By carrier across 2023, 2024, 2025 and 2026, Republic Airways averaged the best on-time rate at 82.9% and Frontier Airlines the worst at 65.8%, a gap of 17.0 points.

Alaska Airlines handled the holiday best relative to its usual record (+3.6 points on average), and United Airlines worst (−2.1).

Year by year, the best-performing carrier with 500 or more flights was Republic Airways in 2023 (92.2%), Hawaiian Airlines in 2024 (83.0%), Hawaiian Airlines in 2025 (90.6%) and Alaska Airlines in 2026 (83.2%).

LAX to SFO and SFO to LAX were among the five busiest routes in every year, so their figures on the year pages are worth comparing across years.

What to do with this

Planning Memorial Day weekend 2027

Planning Memorial Day weekend 2027? On the record so far: fly the Saturday if the dates allow; take a 5am–8am departure; and allow more connection time at Atlanta (ATL) and Chicago (ORD).

On time means arriving less than 15 minutes after the scheduled gate time. Average delay counts delayed flights only; cancellations are a share of every scheduled flight. A holiday is compared with the two weeks either side of it, leaving out days that belong to other holidays. The measurable-effect test asks for 3 points of on-time rate, 5 minutes of average delay or 2 points of cancellations; airports, routes and carriers need 500 flights in the window to be ranked. The US DOT publishes on-time data about two months after the month it covers.
