Coming back from TXL on Novemeber 9th we had a tech stop in Goose Bay. Only took about 45 minutes, but still added on a lot of time to be on a 757. Not to mention once we got to EWR just about everybody who had a connection had missed it, and the EWR staff is not the friendliest, so it was not a fun experience at the transfer desk.

The stop in Bangor was not pre-planned (prior to CGN departure), was on the ground in BGR 40 minutes, and arrived EWR 2hrs18 minutes late (I'm thinking part of the reason was Bangor being out of the way, part flow control into EWR).
The stop in Goose Bay was pre-planned, resulting in a 1 hr 25minute delay into ewr.
