If you still hold an American Airlines or Southwest ticket through the Northeast on Monday, August 3, 2026, the rebooking clocks are open today and they close faster than the storm does.
Both carriers published official weather flexibility for named East Coast airports while thunderstorms and volume constraints continue to shape the day. The rules are not identical, and the American deadline to rebook is the same calendar day as the travel date.
- What changed: American and Southwest opened Northeast weather rebooking for August 3 travel.
- American airports: Boston (BOS), New York JFK, LaGuardia (LGA), and Philadelphia (PHL).
- Southwest airports: BWI, BOS, ISP, LGA, PHL, and Washington Reagan (DCA).
- American deadline: Changes must be booked by August 3, 2026, for original travel that day.
- Southwest window: Rebook or standby within 14 days on the original city pairs.
This is a traveler rebooking story, not another recap of the national air traffic plan. Deep Arrival already covered the FAA August 3 Northeast and Florida delay plan. JetBlue published a separate East Coast fee waiver for August 2 and 3 that we covered on its own stream.
The new material for American and Southwest is the carrier rule sheet itself: which airports count, who is eligible, how far you can move, and when the free change path ends.
American Airlines Northeast severe weather rules
American Airlines lists a severe weather alert for the Northeast United States on its official travel alerts page, with information current as of August 2, 2026.
The named markets are Boston (BOS), New York Kennedy (JFK), New York LaGuardia (LGA), and Philadelphia (PHL). The waiver applies when you are flying to, through, or from those cities on an American Airlines flight.
Eligibility is narrow and easy to misread. You must be booked in any fare class, including Basic Economy, on American metal. You must have bought the ticket by August 1, 2026. Original travel must be scheduled for August 3, 2026. New travel may fall on August 2, 3, or 4, 2026 only.
You may not change the origin or destination city under the free path. You must rebook in the same cabin or pay any fare difference. Changes must be booked by August 3, 2026. Travel must still be completed within one year of the original ticket date, and a fare difference can still apply outside the free window rules.
American points customers to online trip tools first. If the change option does not appear, reservations can process the same eligibility rules. The page also states that if your flight is impacted, the airline will reach out by email and app notification, so check those channels before you abandon a seat that is still operating.
For travelers connecting over Boston or the New York airports, the practical risk is not only a ground delay at the first leg. A short connection after an American arrival into BOS, JFK, LGA, or PHL can evaporate when the national system is already capping arrival rates. Rebooking before you leave home can protect the whole day better than waiting for a same-day recovery bank.
If your ticket is codeshare metal operated by another carrier, do not assume the American waiver applies just because the confirmation shows an American record locator. Confirm the operating carrier before you spend the rebook.
Southwest Northeast weather rules
Southwest Airlines lists a Northeast U.S. inclement weather advisory for Monday, August 3, 2026 on its official travel advisory page.
The Southwest airport list is broader than American’s in the same corridor. Named cities are Baltimore/Washington (BWI), Boston Logan (BOS), Long Island/Islip (ISP), New York LaGuardia (LGA), Philadelphia (PHL), and Washington Reagan National (DCA).
Southwest does not publish the same one-day rebook-by deadline that American uses. Customers holding reservations to, from, or through the listed cities on the corresponding date may rebook or travel standby within 14 days of the original travel date between the original city pairs without paying a change in airfare.
Southwest also states a separate refund path when Southwest cancels or significantly delays the flight and the customer chooses to cancel the trip. That refund language covers the unused ticket even when the fare was nonrefundable, plus optional charges such as Extra Legroom or Priority Boarding on flights the customer does not take.
Most customers can change online or in the app. Getaways by Southwest vacation packages must call the dedicated Getaways line rather than using the standard self-service path. International city callers should use Southwest’s published contact list for the relevant city.
Because Southwest’s rebook window stretches 14 days while American’s free move is only August 2 through 4, a dual-itinerary household can easily make mismatched choices. Align the new dates before you lock either change if both people need to travel together.
How the two rule sheets differ in practice
American is a same-day precision tool. It protects August 3 travel at four core Northeast hubs and forces action by August 3, with only a one-day pad on either side of the original date.
Southwest is a longer recovery tool. It covers six airports, includes BWI, ISP, and DCA that American does not list on this alert, and allows a two-week rebook or standby path on the same city pairs.
Neither page promises a cancel. Both are options if weather and air traffic constraints make the day unworkable. If you are on American into Boston and then Southwest out of BWI later, treat the tickets as separate contracts and fix the tighter American deadline first. A waiver is a risk tool, not a requirement to abandon an on-time flight.
| If you | What to do |
|---|---|
| Hold American travel on Aug 3 via BOS, JFK, LGA, or PHL and bought by Aug 1 | Use American’s online change path today; new travel must fall Aug 2 to 4 in the same cabin or pay the difference. |
| Hold Southwest travel on Aug 3 via BWI, BOS, ISP, LGA, PHL, or DCA | Rebook or stand by within 14 days on the original city pairs, or keep the seat if the day still works. |
| Need both people on matching new dates | Reconcile American’s short window with Southwest’s 14-day window before locking either change. |
| See a Southwest cancel or major delay and no longer want to travel | Use Southwest’s refund path for the unused ticket and paid optional extras on flights you will not take. |
| Only hold JetBlue on the East Coast this weekend | Do not use these two pages; follow JetBlue’s own August 2 and 3 East Coast waiver stream instead. |
- Act same day on American: The free change path for August 3 American travel ends on August 3, so complete eligible rebooks before the day closes.
- Confirm operating carrier: Codeshares and partner flights may not inherit American or Southwest self-service weather rules.
- Protect short connections: If your plan depends on a tight BOS, LGA, JFK, or PHL bank, move earlier rather than hoping the recovery seats survive the afternoon.
- Use the longer Southwest pad carefully: A 14-day move is useful, but inventory on the original city pairs can still thin as other customers rebook.
- Keep receipt trails: Screenshot the alert page, the new itinerary, and any cancel notice if you later need a refund or fare difference review.
For airport context on the American side of this corridor, see Deep Arrival’s Boston Logan airport guide and the American Airlines planning hub. Southwest customers who need product rules after a rebook can use the Southwest Airlines planning hub.
What remains uncertain is how long individual ground stops and ground delay programs will last into the evening, and whether either airline will extend the written windows if residual storms linger. Until a carrier updates its alert page, treat the published dates and airport lists as binding.
Does the American waiver cover Newark or Washington Reagan?
Not on the current Northeast severe weather alert text. American’s named airports for this event are BOS, JFK, LGA, and PHL only. Southwest separately lists BWI, ISP, and DCA among other cities.
Can I change my American destination city for free?
No. American’s free path for this alert does not allow origin or destination city changes. Stay on the same city pair and same cabin, or pay any difference that applies.
How long does Southwest give me to rebook?
Southwest allows rebooking or standby within 14 days of the original travel date between the original city pairs for eligible August 3 itineraries at the named airports.
Is this the same story as the FAA August 3 delay plan?
No. The FAA plan describes expected air traffic constraints. These American and Southwest pages are the passenger rebooking contracts that decide whether you can move without a change fee today.
What if JetBlue is my only carrier?
Use JetBlue’s own East Coast weather fee waiver for August 2 and 3 rather than these two pages. Carrier weather rules do not transfer across brands.
