What will AIRLINE travel be like in 50 years?

Today I read an article about an airline charging money to use a pillow and a blanket.

One day air travelers will look back at today’s airline travel and laugh. Things are getting ridiculous.

Technologywise and servicewise, what will be the big changes in 50 years?

Will 747′s still be around in 50 years? What craft will be the norm? What about the accomodations and comfort? What about the time of travel?

Many questions rolled up into one question. Would like to hear your views. Thanks!
Great answers so far. Lots to think about and consider.

SCRAMJET would be unfathomable to a person in, say, the Dark Ages. If you tried to explin the concept/science, you would be considered evil.
