I get you guys points.. My thinking was with the new technology available ( wing designs, powerful GE90 Engines) I thought you could take a big tank to cruise Altitude ( in a timely manner) save fuel and live happily ever after. Instead your step climbing and burning fuel that could be saved IF you could get to Cruise.
Was working a 77-300 departure today and a pilot told me the 300 has wing issues at Altitude that it can't fly high altitudes until fuel load is burned down. I didn't low this and thought with the GE90 engines that this thing was a power house but he said power isn't the issue its the wing...
Any real 300 pilots care to alleviate?
