Sixchannel - I look forward to hearing how you get on. I agree that car parking is stupidly expensive at BHX however cramped facilities? I'm guessing you're one of those pax that dumps themselves on a seat in the dark no natural light departure lounge as soon as they have exited the shopping mall chicane? Next time, take a short walk up to the gates and you will have a huge airy pier with great views of the airfield mostly to yourself, a lovely quiet Costa and loads of seating.
I have nothing against EMA but in my experience if there are more than a few flights boarding around the same time, the security queue is huge and there is absolutely nowhere to sit once through their version of a shopping mall.....
