JetBlue cancels 872 flights in four days, still leading U.S. cancellations

JetBlue has canceled 872 flights over four days and is still leading U.S. cancellations on Wednesday with JFK at 58, Reagan at 41, Boston at 35, LaGuardia at 31, and Newark at 24, DCA departure delays have reached 76 to 90 minutes from the first weather complex of the morning with the FAA's 2 PM ET convective wall forecast putting twelve hubs in its crosshairs, Tropical Storm Bertha is 45 miles from the Mississippi River mouth at 50 mph with southeastern Louisiana landfall expected tonight, and no carrier has issued a Bertha-specific Gulf Coast waiver.

JetBlue's fourth day: 872 canceled, crews still stranded

JetBlue has canceled 872 flights over the last four days according to FlightAware, and the carrier was once again among the top for U.S. cancellations on Wednesday. Across all airlines, the airports with the most departure cancellations on July 22: JFK 58, Reagan National 41, Boston 35, LaGuardia 31, and Newark 24, per thetravel.com.

The crew-scheduling collapse that ALPA Captain Wayne Scales described on July 20 is still dragging on the recovery. Scales said JetBlue's Crew Scheduling department was "effectively unreachable" with hours-long hold times, crews were left stranded at airports overnight without hotel accommodations, and the scheduling system has collapsed "week after week, weather incident after weather incident." With pilots out of position and hitting legal rest limits, cancellations are compounding even on clear-weather mornings like this one.

JetBlue's travel waiver covers 11 airports (BWI, BOS, ISP, JFK, LGA, EWR, ORF, PHL, RIC, DCA, HPN) for flights July 20 through 22, with rebooking available through July 26. Tickets must have been purchased before July 17. Group bookings of 10 or more must call 1-800-JetBlue rather than using the online Manage Trips tool.

DCA departure delays hit 90 minutes as the Northeast weather wall approaches

Reagan National is reporting departure delays of 76 to 90 minutes due to weather as of 10:33 AM ET, the first significant weather impact at a DC-area airport this morning. LaGuardia has 31-to-45-minute weather departure delays and Teterboro has 45-to-59-minute delays. San Francisco has a routine ground delay program averaging 31 minutes from runway construction.

No ground stops are active right now. The Northeast airspace cleared overnight after Tuesday's ten-airport ground stop siege. But the FAA's operations plan puts the next convective wall at 1800Z (2 PM ET), with ground stops or delay programs possible at JFK, LaGuardia, Philadelphia, Newark, Teterboro, Dulles, Reagan, BWI, Orlando, Tampa, Miami, and Fort Lauderdale. The next planning webinar is at 1515Z (11:15 AM ET), and the ops plan typically updates two to three hours after.

The question this afternoon is whether the 2 PM wall fires on schedule or fizzles. It fired hard yesterday, producing ground stops at all ten Northeast hubs. Before that, the morning convective forecast had fizzled for 14 consecutive days.

Bertha is 45 miles from the Mississippi River mouth with landfall tonight

Tropical Storm Bertha's center was 45 miles northeast of the mouth of the Mississippi River at 11 AM ET (Advisory 13), moving west-northwest at 6 mph with 50 mph sustained winds. The NHC describes the center "wobbling south of the Mississippi coast" with tropical-storm-force winds extending 105 miles outward. A gust to 49 mph was reported at Pensacola Naval Air Station.

A Tropical Storm Warning covers the western Florida Panhandle to Morgan City, Louisiana, plus metropolitan New Orleans and Lake Pontchartrain. A Tropical Storm Watch extends from Morgan City to Sargent, Texas, and includes Lake Maurepas. AccuWeather forecasts the first landfall around 8 PM ET tonight in southeastern Louisiana, with the center tracking near or over New Orleans before a second landfall in Texas on Friday.

The 12-hour NHC forecast puts Bertha at 45 mph on the Louisiana coast by 2 PM ET, weakening to 40 mph overnight and dissipating over Texas by Friday. AP News reports beaches closed from Florida to Mississippi.

No carrier has issued a Bertha-specific Gulf Coast waiver. When Tropical Storm Arthur struck the same region in June, American, Delta, Southwest, and United all issued penalty-free rebooking waivers covering Pensacola, Panama City, Mobile, New Orleans, and Houston. The same playbook is expected once Bertha's conditions reach Gulf Coast airports, which industry analysts say could happen at Mobile and Gulfport on Wednesday and New Orleans on Thursday as wind gusts of 40 to 60 mph threaten ramp operations.
