Just to tie this thread up...
Because my trip is quite important I decided to ditch the Easyjet flight and fly into Bham the day before, stayover with my friend, then travel down to Stansted together for the Ryanair flight. So I'll never know if it was do-able!
If I would have missed the 11:05 Ryanair flight to Altenburg the next flight would be around 16:00 the following day!
Just too risky!
Cheers all.
