EMA does not have a multi-story car park so shall we compare like for like shall we.
For four days surface parking within walk of the terminal it is £28.80 at BHX and £36 at EMA.
Prior to EMA becoming 'low cost' I could park at EMA for £18.00 for four days. Overnight it went to £32 and now it is £36.00!
So now I don't bother.
There is also a minimum charge of £36.00 in the medium stay car park so you can forget about the £8.00/day comparison.
Furthermore at BHX you do not have the nonsense of not being able to collect or drop off outside the terminal.
