Apart from the obvious FRA, AMS, CDG and BRU are there any European cities one can fly to from MAN early in the morning and return late at night, for a good day trip? I would like to do DUB, but the flights seem to return too early to get an early evening meal in.
Dublin on Ryanair (out 0755 back 2215), only certain days for the late return flight though, mostly very cheap.
Munich on Lufthansa (out 0700 back 2125), have to pick the right dates to get a good fare though.
Geneva on easyJet (out 0640 back 2135), have to pick the right dates once again.
That's three from the top of my head that are affordable (under £100), and I'm sure there's plenty more.
During the summer the likes of AGP/ALC/PMI/IBZ/MAH and even the Canaries are all do-able for a day trip on the various charter and low cost airlines.
Look around, there's plenty of stuff
Even more if you're willing to do 'connection' flights on FR (ie MAN-RYG-CRL-MAN)
