Having just been delayed over 24 hours in Frankfurt, where queues to rebook flights were in excess of three hours, where there were poor queue managment, limited help, poor facilities or information for stranded pax , escalators not working etc etc. Manchester was a palatial breeze to arrive back into. gate 25 to rail station 20 minutes.
They (FRA) had a fraction of the snow we have had in Manchester- but the airport ground to a halt for hours. ( ice & de-icing issues)
Manchester has a fraction of the resources some other places have and don't do a bad job.
The nature of air travel these days and the drive for low cost everything will mean that people will have good and bad experiences wherever they are, Manchester being no exception.
