I fly B6 regularly on Winter transcons and have only had 1 tech stop, oddly enough on a JFK-LGB flight. We diverted to ABQ and were in and out within 30 min, closer to 20 min I think. The ground ops folks were waiting for us with the fuel truck and air stairs in the remote location. Even the Captain kept remarking about how stunned he was that the process was so quick.

I also used to fly between JFK-PDX regularly and have never had a fuel stop on that route.

It really is a crapshoot. Just expect the worst and hope for the best and bring a good book with you.
