How many European start up airlines carrying passengers plan to use aircraft that are around 30 years old?
Reliability and punctuality are the reasons for not flying old airframes. Ignore the maintenance costs, huge damage can be done to small airlines that suffer from very poor on-time performance. Reputations are won and lost on this single issue.
Good luck to Flywho.
How many folk on here drive a 30 year old car, my guess, not very many!
