Gatwick Airport to London "bargain" train tickets

If you book through trainline.com, there are a load of options and it also sets out the restrictions on various ticket types.

If you have an oyster card or a Bank Card you can use in the UK without fees for Tapping on and off the price off peak is £9.50

u12 are free on the underground. U5 are free on the Thameslink service.

as noted by sgarvan no they are not.

The only way round it would be to get a child visitor oyster card,

or if you can use an address in the UK you can use them to get a proper child oyster card before hand, need probably a month to organise it.

My wife was lived in Marylebone last year and I constantly flew over to Heathrow.

Like this post I would advise people never to use the Heathrow express. I did quite often as I would get the very early morning flight.

The tube journey on the Elizabeth line was/is considerably cheaper (HE prices are seriously expensive).

All considered the tube service is only 10-15mins longer.

Nice one! 4 of us heading over in a couple of weeks, for the night, for the boxing, and traveling from LGW, and staying in Shoreditch. This offer will come in handy
