I did a MR yesterday, as I found a pretty good deal in F (fare classes A,A,G,G), on the MCO-ATL-PHL-ATL-MCO route, with same day turn-around.
The flight on the first leg, MCO-ATL, was on a reconfigured 752 with new F! Surprisingly, I found the new F to be significantly narrower than the old F! My last leg was on an 'old' 752, with the old F seats, and I found them to be more spacious (seat-width).
Has anyone noticed this, or am I the only one? Or am I missing something here?
