Totally agree. Some of the fares are really cheap these days. For example a return flight from Manchester to Dublin booked two weeks in advance is £20. That's a journey that can only be done by flying for one hour or driving for two followed by a three hour ferry.
Or perhaps even better, a return from Manchester to Nürnberg for ~£30 in 2 hours instead of a 14 hour drive plus ferry. The fuel for that alone (not including the ferry) would cost £170.
I just don't understand the complaints!
Booking a few months in advance I can get a return trip to the otherside of the world (Australia) for under £700 and get there in less than 24 hours. I find that incredibly cheap and would be mindblowing just 20 years ago.
