Our plane from Orlando arrives at 8:40 and I wish to book my train tickets to travel home. Given that we have to go through customs and baggage collection, at what time are we likely to be out of the airport and at Manchester airport train station?
I have flown into Manchester many times. Sometimes it take forever to pass through immigration. From my experience it depends on what day of the week and time of the year. In summer, it will take longer for obvious reasons. Also, if you are not a EU citizen it will take longer to pass immigration.
With regards to baggage collection, Manchester is pretty good compared to some airports i have arrived at.
I normally allow 1.5 hours after the scheduled arrival time for booking onward travel. Flights don't always run on-time.
