The 380 cruises a little quicker, but it goes straight up and has a lower TAS.
The 74 cruises a tad slower, but stays lower for longer with a higher TAS. So it used to quite often overtake underneath.
I know what I’d rather fly. I also know what I’d rather pax in.
The 74 will probably still be flying on one form or another when the 380 is not.
