Boston Logan's ground stop extends to 6:15 PM and Denver enters a 100-minute ground delay as the Northeast storm siege eases

Boston Logan's ground stop has been extended to 6:15 PM ET from thunderstorms over the field with roughly 170 delays and more than 70 cancellations on Wednesday, Denver went into a ground delay program at 5:30 PM ET averaging 101 minutes with a maximum of 164 minutes from monsoon-charged thunderstorms on the Front Range, the rest of the Northeast is on time with JFK, LaGuardia, Newark, Philadelphia, Reagan, Dulles, and BWI all clear, Tropical Storm Bertha made landfall in southeastern Louisiana at 3 PM ET with 45 mph winds and the warning extended westward to Cameron but no Gulf Coast airport has gone into ground stop and no carrier has issued a Bertha waiver, and JetBlue has canceled 872 flights over four days with no recovery timeline from its crew-scheduling collapse.

Boston Logan's ground stop extends to 6:15 PM, Denver in a 101-minute ground delay

The FAA's afternoon convective wall, forecast at 2 PM ET to put twelve Northeast hubs in its crosshairs, mostly fizzled. What actually fired was narrower and shifted west.

Boston Logan is in an active ground stop from thunderstorms over the field, expected to end at 6:15 PM ET per the FAA's NASSTATUS feed as of 5:22 PM EDT. The stop was initially set to expire at 4 PM ET in the FAA's operations plan ADVZY 127 (signed 3:39 PM ET) but has been extended. Logan has accumulated roughly 170 delays and more than 70 cancellations on Wednesday, WBZ NewsRadio reports, on top of Tuesday's 315 cancellations and 437 delays when the FAA put Logan in a ground stop around 8 PM.

Denver went into a ground delay program at 5:30 PM ET (ADVZY 132, signed 4:23 PM ET), averaging 101 minutes with a maximum of 164 minutes, formally running until 11:59 PM ET. The cause is thunderstorms on Colorado's Front Range. CBS Colorado (published 5:12 PM ET) reports departures to Denver are being delayed by about 100 minutes, with the airport expecting the delay to remain in place until just before 10 PM. The FAA advisory notes the possibility of revisions after 6:30 PM ET. An NWS flood advisory is in effect for areas southwest of the Denver metro.

Salt Lake City also has arrival delays up to 30 minutes (ADVZY 128) from thunderstorms and variable gusty wind, running through 10 PM ET.

The rest of the Northeast is on time. Flightcheck shows JFK, LaGuardia, Newark, Philadelphia, Reagan, Dulles, BWI, Atlanta, Chicago O'Hare, Dallas-Fort Worth, and Charlotte all operating normally as of 5:22 PM EDT. The FAA's current operations plan (ADVZY 127, signed 3:39 PM ET) confirms the SFO ground delay program (construction-related) has been cancelled.

The plan does flag DCA as a possible ground stop through 8 PM ET, CLT as possible after 5 PM ET, and staffing triggers at ZDC Area 6 (7:30 PM to 10 PM ET) and ZID Area 4 (5 PM to 10:30 PM ET), though the FAA says no impacts are expected from the staffing triggers at this time. The next FAA planning webinar was at 5:15 PM ET.

Bertha made landfall in Louisiana, no airport disruption

Tropical Storm Bertha made landfall on the eastern side of St. Bernard Parish, Louisiana, around 2 PM CDT (3 PM ET) Wednesday, the National Hurricane Center reports in Advisory 14 (4 PM CDT). The storm is 25 miles southeast of New Orleans with 45 mph sustained winds and 1000 mb pressure, moving west at 7 mph.

The tropical storm warning was extended westward to Cameron, Louisiana. The warning now covers the Alabama/Florida border to Cameron, plus Metro New Orleans and Lake Pontchartrain. A tropical storm watch extends from Cameron to Sargent, Texas, and includes Lake Maurepas. New Orleans Lakefront Airport reported a sustained wind of 36 mph with a gust to 44 mph.

USA Today reports Bertha does not appear to be making a significant impact on air travel. No Gulf Coast airport has gone into ground stop, and Louis Armstrong New Orleans International (MSY) was operating with very low delays and zero cancellations this morning. No carrier has issued a Bertha-specific Gulf Coast waiver.

The NHC forecast discussion (Forecaster Berg) says Bertha's center will move near or along the Louisiana and upper Texas coasts through Thursday, then inland into Texas Thursday night. Bertha could maintain tropical storm intensity until it reaches the upper Texas coast Thursday, then dissipate inland by Thursday night or Friday. The next intermediate advisory is at 7 PM CDT (8 PM ET).

Recommend.com projects the heaviest aviation impact at New Orleans and Lafayette on Thursday, with Houston-area airports potentially affected Friday and Saturday as Bertha's remnants track into Texas. Wind gusts of 40 to 60 mph could pause ramp operations at Gulf Coast airports.

JetBlue: 872 canceled over four days, no recovery timeline

JetBlue has canceled 872 flights over the last four days and is still leading U.S. cancellations on Wednesday, according to FlightAware data cited by TheTravel. Wednesday's departure cancellations by airport: JFK 58, Reagan 41, Boston 35, LaGuardia 31, Newark 24.

The Air Line Pilots Association says JetBlue's Crew Scheduling department was "effectively unreachable" over the weekend, with pilots experiencing hours-long hold times and crews left stranded at airports without overnight accommodations. Captain Wayne Scales, chairman of the JetBlue MEC, said the airline's scheduling system failures went beyond weather. Hoodline reports nearly 1,000 canceled flights over the weekend, with customer-service lines stretching through terminals at Logan and other East Coast hubs.

JetBlue's travel alert covers 11 airports (BWI, BOS, ISP, JFK, LGA, EWR, ORF, PHL, RIC, DCA, HPN) for travel July 20 through Wednesday, July 22. Passengers can rebook through Sunday, July 26, with no change fees or fare differences. Tickets must have been booked before July 17. No recovery timeline has been announced.

Rebooking deadlines and the Bertha waiver gap

American Airlines' rebooking deadline is today, July 22. Changes must be booked today for travel July 20-22 through 9 airports (BOS, BWI, DCA, EWR, HPN, IAD, JFK, LGA, PHL), with travel completed by July 24. Check aa.com.

Delta covers the same 9 airports for travel through July 22, with rebooking through July 25. Check delta.com. United covers 8 East Coast airports (EWR, JFK, LGA, PHL, BOS, BWI, DCA, IAD) for travel through July 21, with rebooking through July 23. Check united.com. JetBlue covers 11 airports for July 20-22, rebook by July 26. Check jetblue.com. Southwest has a travel advisory for July 21 covering BWI, BOS, LGA, PHL, and DCA.

No carrier has issued a Bertha-specific Gulf Coast waiver. When Tropical Storm Arthur struck the Gulf Coast in June 2026, American, Delta, Southwest, and United all issued penalty-free rebooking waivers 24 to 48 hours before conditions arrived at affected airports. That window is now for Thursday's expected New Orleans and Texas impact, meaning Gulf Coast waivers could appear tonight or Thursday morning if carriers follow the same playbook.
