JetBlue On-Time Performance in 2026

The headline number

JetBlue routinely posts among the lowest A14 percentages in the US — typically in the high 60s — driven by JFK and BOS exposure to ATC flow programs.

Why the number is what it is

• 60%+ of JetBlue capacity touches NYC or BOS.
• Both airports run frequent Ground Delay Programs.
• JetBlue's narrow-body fleet has limited flex when one tail goes down.

Where JetBlue does better

• FLL banks — strong morning, ok afternoon.
• Mint transcon JFK→LAX/SFO — solid OTP relative to leisure volume.

Booking advice

1. Avoid PM departures from JFK in summer.
2. Pin the inbound aircraft; one slip cascades.
3. Build a generous connection at JFK (90+ minutes minimum).

What FlightyFlow shows for B6

We weight active GDPs at JFK and BOS heavily for any JetBlue prediction. Expect amber/red chips during NYC afternoon storms even when the airline still says "On Time."
