You've done all anyone reasonably can mate just have to hope for the best. I always have checked luggage to worry about too so connections are a major headache. With hand luggage I've even seen people bussed from one plane direct to another on same airline when time is very tight. Have faith !Never used them - but part of my ticket allows me to catch an earlier flight on the same day, so could do that and if it's cancelled ask them to put me on the one I should have been on. Got two shots at getting to Barcelona for 1740, the flight I have booked (around 12-ish), if that's cancelled then there's one around 1420 and then the one which really would be a tight squeeze - around 1540. Once in Barca if the 1740 to Manchester is cancelled then I shall beg/plead them to find me a seat on the Easyjet that flies later!!
The reason timing's important is that there's NHS paid-for cover for mum up until midnight Weds, any time after that I'm beggering about trying to find flights and cover for mum 1000 miles away; stress I could do without on a rare break!!
It IS a budget airline (but then again British Airways is usually shit) so I'm not expecting a free shag from an attendant, just hope they do the job with time to spare. They are quick to respond to twitter though!!
