Start off at stupid o'clock of a morning and all wrapped up and home to bed by 8.30pm of an evening ... What's this all about.
0600 departure, 0500 (ish) check-in, live in Cambridge then 0400 wake-up, live an hour outside of Cambridge then 0300 wake up ... How long before the travelling public catch on that it's far more sociable to travel to/from NWI, STN, LTN or BHX?
Agree with others, neither AMS nor DUB has both a morning and evening service so both routes seem doomed to fail.
And presuming that this is a single geriatric turbo-prop aircraft operation I'd like to bet they don't have a sufficient spare parts back-up at Cambridge!
