Not internal flights from a local airport. Takes 30 mins from entering the airport to boarding or quicker. It's 2 hours all in including the flight (worse case) vs a day on the train.
doesn't it usually tell you when you book a flight that boarding closes 40minutes before take off?
okay it doesn't seem like that actually happens but you would be an idiot to turn up at a local airport just in time for boarding to open.
newcastle airport is tiny, usually security has no queue, one time decided oh it never has queues anyway, turned up at the airport doors 40minutes before take off and barely managed to catch the flight because for once security had a lot of people, and most people are morons who take forever to actually empty their pockets, take off their belts, get the electricals out etc.
I'd never turn up to an airport again after the luggage drop off for my flight has closed which is a long time before the gate has been announced.
you don't give your self much room to catch the flight even if you don't have luggage.
in my experience train over plane, but I don't travel on UK trains which may be far less superior compared to the swiss trains which are double decker, pretty god damn long, have a restaurant car and are 80% of the time exactly on time.
I do a 3.5hour train to zurich from geneva even though the plane even including airport time would probably be 1-1.5hours quicker and about the same price..., no stress, can choose where to sit and don't feel like my privacy is being invaded by someone elses arm.
