You've clearly had a bad experience on NXEC and you've also clearly never used Megabus. "And I really mean that"
.
I travel to Newcastle and Leeds on business from London at least once a fortnight to each destination and, whilst my preference is flying (as I love flying) I'm afraid flying does not touch rail to either destination.
Heathrow is a miserable place to travel to and from.
Flights are less punctual than rail (yet air users seem to just accept this - why?)
Rail does not have the ludicrous security of flying (the queue at Newcastle airport is particularly tedious).
Flying does not have Wi-Fi.
Rail does not have the "hidden surcharges" that dog flight tickets.
You can use the phone on the train.
You can have a proper meal at a table on a train.
Rail of course is also more environmentally sound but thats a red rag to a bull on PPRUNE.
Etc....
I love flying but I have to dispense with the rose tinted spectacles - Yeadon London via Heathrow does not come close to rail for business.
Now Docklands and Gatwick might be interesting though.
