Aren't AMS and DUB still 757's?

AMS is currently a 763 but will switch back to a (LAA) 757 when DFW-AMS begins for the season on May 4. DUB is currently a 332.

Definitely not the case for PHL-AMS. Per EF and AA.com 757 service resumes on May 4, the day DFW-AMS starts for the season (with a 772). Overall this does represent a capacity increase to AMS for all seasons. Last year we had the lone 757 from PHL year-round and a 767 from DFW during the summer. This year, we get a 767 in the winter and a 772+757 combo in the summer.

Later this year NON-STOPs (64 and 65) between JFK and ZRH will no longer run. One alternate for NYC to ZRH is via PHL; depending on the day, the connection can be as little as 1 hour and as much as 8 hours; for the first connection if you miss the PHL-ZRH there is NO other option, for the 2nd connection...8 hrs in PHL:rolleyes:
On the NS flts JFK-ZRH many pax are making connections--hence a NS is one leg less. Another option is JFK-LHR-ZRH--LHR is not a "friendly" airport for connections.:p

AA giveth and AA taketh away
 

On March 26, I booked a ticket from JFK to IAH departing late (approx 6:50 pm) for July travel.

On March 26 ... less than 12 hours after it was ticketed, AA send notification of a schedule change, and now it's impossible to get to my destination that same day.

Yes, I know, schedule changes can happen at any time. But 12 hours after booking?

Why not? Why not 12 minutes after booking, or 12 seconds after booking? You booked to a schedule and then a new schedule went live.

The JFK-ZRH nonstops have already been moved to PHL as of last weekend--the last JFK-ZRH flight departed on March 24, and the plane turned around in ZRH for PHL the following day.

I just looked at PHL - AMS and its a 767 in S2018.

Ah, I see what's happening. The 757 operates for 1-2 months starting May 4, then the 767 resumes service sometime in June. My oversight!

Couldn't a schedule change 12 hours after booking be a blessing as opposed to one month before you travel? This way, you can cancel the ticket outright and create a new itinerary. You have options when the schedule change occurs so soon after booking and your travel date is somewhat far in the future.

You're exactly correct! I have a customer near MCO who is small enough to matter, but not large enough to go out and visit regularly. I was able to rebook the flight to a late-night JFK-MCO, then the next evening MCO-DFW-IAH, thus picking up a free day-trip to MCO.

Now I'm hoping for schedule changes on all my other upcoming trips too, LOL

Unfortunately, no business traveller from NYC is going to connect in PHL for a flight. We have too many options. Most will just take LX, DL or UA to ZRH. There are already 6x a day from NYC.

Its too bad that AA isn't adding more TATL destinations from JFK. DL keeps growing. Gets hard to ignore.

Unless you want a very long layover, there is only one flight on a regional jet from DCA-PHL that connects with the TATL block. Gven the number of people in DC, makes me think they'd rather you go through LHR on BA or AA somehow than take the AA metal to the continent. For the early flights from PHL (ATH/MUC/MAD) the only one stop option requires you to have a 7 hour layover. Makes no sense to me except that I guess AA doesn't really want us using PHL.

I wouldn't necessarily say that. I've been on PHL-LGA a few times (ironically, to connect in LGA) and it's been chock full every time of NYC originating/departing passengers. There is a reason AA continues to run PHL-LGA flights, despite the short distance, and now operates PHL-JFK as well. People are connecting. Nevertheless, I would say "most" business passengers aren't going to connect, but some clearly are.
