A 0725 arrival into Dublin is 3 hours away from the first EI ta flight. Plus the timings for FR on that route are pretty lousy as it is.
There is a fairly significant amount of time required to connect to a US flight due to CBP.
FRs timings on LBA are so poor that I now fly to MAN and take the train when going to Leeds - multiple times a year. I doubt I'm the only one either.
