At T2/T3, head towards the HEX ticket machines on the -1 level, then turn around when you're there and the normal collection machines are on the wall behind you.
I'm coming in on BA from MAN so I have to check what terminal I'm landing in. That being said I know where the HeX office is and it's no where near the tube...That doesn't sound very efficient to get a tube ticket + train ticket San Pancras to Ashford then trek all the way down to the tube, or am I missing something blatantly obvious.
