That was prior to me coming back. I'm 756 as well.

The rumors I hear:

Select U-boat 757s (my term for UAL jets, and meant as an endearment, not derogatory) may get GPS and maybe CPDLC/ADS-B. This is so they can do oceanic trips; freeing stretch 737s to do domestic, since running an APU to Hawaii doesn't make them cheaper than the 757.

The avionics upgrades you mentioned for 767-300s. They can already do the trips, but it would make it easier and more reliable/interchangeable.

The 14 jets are mentioned in the inflight mag under "Our Fleet," and there is a picture. They already have winglets.

Would be interested in the newsletter, if you can post it.
