Beleagured airline JetBlue is grounding all flights due to arrive at New York JFK for the remainder of Tuesday as widespread thunderstorms cause havoc across the Northeast, leading to FAA-mandated ground stops in Baltimore, Boston, Newark, New York, and Washington Dulles and Washington National airports.
According to flight tracking service Flight Aware, JetBlue has already canceled 257 flights on July 21, representing a quarter of all flights the airline had planned to operate on Tuesday. A further 373 flights have been severely delayed, and the number of cancellations is expected to rise in the hours ahead.

In an internal memo leaked by aviation insider JonNYC on X, staffers at JetBlue were told that arriving flights were being delayed on average by nearly 4 hours. The memo added: “Many flights are seeing even longer delays from earlier ground stops. LGA [LaGuardia] is experiencing similar issues, and BOS [Boston] is also ground-stopped.”
“Given this backdrop, we’ve made the decision to cancel the vast majority of our remaining JFK arrivals for the evening that are not already inbound to the airport. We plan to continue to operate the small number of departing flights that remain on the books for today.”
The latest information from the Federal Aviation Administration is that New York JFK is experiencing departure delays of around 90 minutes, while arrivals remain suspended due to thunderstorms in the region.
JetBlue has faced days of massive disruption with the airline cancelling 147 flights on Monday, 293 flights on Sunday, and 307 flights on Saturday.
In a statement, the Air Line Pilots Association (ALPA), which represents JetBlue pilots, slammed the carrier, saying that the “conditions for customers were often made worse with unnecessary and extensive delays across JetBlue’s entire network.”
Capt. Wayne Scales, chairman of the JetBlue Master Executive Council, added: “JetBlue’s Crew Scheduling department was effectively unreachable, with pilots experiencing hours-long hold times. Many pilots and crews were left stranded at the airport as the Company failed to even provide overnight accommodations.”
Other impacted carriers by the severe weather across the Northeast include American Airlines, which has been forced to cancel 314 flights on Tuesday, although given the scale of AA’s operation compared to JetBlue, this represents just 8% of its entire schedule for the day.
As has already been suggested by Capt. Scales, the next challenge facing JetBlue is ensuring it can recover from today’s disruption without suffering an operational meltdown.
Any disruption of this scale strikes, crews, and airplanes are left out of position, meaning that even when the bad weather clears, the airline isn’t able to recover straight away.
What we have seen in the past is that an airline is much more likely to suffer a full operational meltdown if it loses track of where its pilots and flight attendants are across its network. That might sound impossible, but this is exactly what occurred in Southwest’s Christmas Holiday meltdown, and the more recent CrowdStrike outage that sent Delta into meltdown.
What is worrying is that ALPA says that JetBlue crews were struggling to get in contact with the airline’s scheduling department over the weekend. With ALPA claiming that pilots and flight attendants have been left without overnight accommodation, even once JetBlue tracks them down, they won’t be able to go straight back to work because they won’t be considered rested.
