I find T1 OK, but getting into it is a pain. I am SLF and used bmi regularly from Teesside, then they messed around with the flight times making it inconvenient, now they have closed the route. Also closed Leeds, the next nearest airport. Can't see me using them anymore, LHR is not convenient to get to from the North East, so it's a boost to KLM and Amsterdam and National Express.
Worst thing bmi did was abolish business class, that was the beginning of the end as far as I can see.
Best wishes to all the Teesside crew who were always professional and friendly.
