Earlier quoted context omitted.
Different mindset. BonBook is targeted at travelers solving logistics problems who make lots of repeatable decisions and fly often (eg. need to be in X at Y). No saying what can be done with time.
While that's a good point, I think it would be wise for them to incorporate budget airlines if they are looking at the European market. There are so many routes that are served exclusively by budget airlines.
BonBook does more than just booking (eg. one-email changes) and many budget airlines make this difficult with their restrictive fare rules.
