I was on UA97 TXL-EWR on the 752 yesterday (Sunday), and we had a fuel stop in Bangor.

I was flying TXL-EWR-LAS-LAX (with about a 2 hr layover in EWR), and UA proactively confirmed me (on Saturday, without me calling) on a EWR-LAX non-stop that left about 4 hours after my scheduled EWR arrival (in addition to keeping me on my original flights). I received no e-mail or phone call about this change, I just happened to see it in my reservation earlier. I called the premier line to figure out what was going on, and after 20 minutes they finally figured out that they were protecting me on the later flight since they were anticipating fuel stops, but couldn't actually confirm that there was going to be one.

Upon arrival at TXL on Sunday morning, the counter agents were unaware whether there would be a fuel stop (they also didn't really see my other booking option, or were confused by the LAS and LAX similarity).

After getting on the plane, the FAs & pilot then informed the pax of the fuel stop. Quite a few unhappy pax apparently weren't aware of this, and also weren't sure what this meant for their travel plans. Had I not been watching my reservation I too would've been pretty clueless (and worried).

The fuel stop in Bangor was only about 40 minutes (which I think would've been less than any connection in the EU so you didn't have to make the fuel stop), then we were held on the ground (probably thanks to ATC) just shy of the runway for 15 more minutes. We then seemed to do a little meandering around EWR and landed about 1 hr 40 min late.

After waiting what was probably 20+ minutes for baggage to arrive, I'm pretty sure most people's connections would've been toast. When I tried to get a new tag for my checked bag that reflected my new itinerary, they directed me to the "International Connections" desk which had a massive line and only a GS & GF priority lane. Instead, I just went upstairs and went to the premier check-in/bag drop and got a new label and BP there.

I think a pax with no status would've missed any connection in EWR that was less than 3-4 hours, and who knows whether UA did any proactive rebooking for them.

On the somewhat bright side, on arrival at EWR I had an appreciation e-mail waiting for me. Offered $200, 9000 miles, or 10% off my next flight.

I was only flying through LAS to try to increase my upgrade chances, but it wasn't going to work this time around, so I don't mind the rebooking on the direct EWR-LAX flight, especially since it arrived before my originally planned EWR-LAS-LAX itinerary.
