The drawbacks to the 75T fleet:

1. No GPS

2. No ETOPs

3. Pratts are 37500 lbs thrust; Rolls are 42,700.

4. Interiors have TV monitors hanging in the aisle; even medium height pax bang their craniums.

The cost to refit all of this is high.

I would like to see them get some more RR ETOPs jets, but I know it won't happen.

If Airbus made a 321 with a slightly stretched wing and higher thrust? You'd have your 757 replacement.
