I think that in the future we will see larger and larger aircraft as the demand for airtravel increases. The reason for this is because we already have more people flying, and with already crowded skies, the need for larger jets is great to clear up sky congestion. What we will eventually see is ONLY twin-jets. They will be cheaper to operate, and be super quiet. Kinda like sitting in first class of an MD-80 on take off. I predict that we will see 747X sized aircraft or larger operated with only two MASSIVE engines. The service will continue to get better and better and I think that eventually, we will see airlines go back to the way they were in the golden years of flying. Mabye no piano bars, but definitely an improvement on whats out there now.
