Actually, it looks like 3 hours is the standard for this journey. Here is some helpful info:

I would use the BA shuttle. If they booked the ticket, they should have some responsibility for helping you make your connection. If something goes wrong and you miss your connection you should have an easier time dealing with BA if you’ve used their shuttle.

So you’re ticketed on two separate journeys? Or, you will start at A, arrive at Heathrow, depart from Gatwick, and arrive at D — and BA booked you that way all on one ticket?

If the latter, then BA should pay for your transfer.
If the former, then you should pay for the transfer.

Either way, I think I’d take the BA shuttle, too, as long as it does not cost significantly more than NEx (if you have to pay).

Hi Don. It’s the latter. That’s the way that BA booked it- I leave SFO to go to Heathrow and then connect in Gatwick for a flight to Split Croatia.

I’d use the BA shuutle regardless of the price. Then you can’t really be at fault should you miss the connection.

Sadly you do infact have to pay and it is GBP 16 which is a discount with you BA ticket.The ba shuttle is the nex shuttle.BA canceled there shuttle back in 2002 which was in fact free..

Having to pay for this, if BA booked it that way, is not acceptable IMHO. BA should pay for it. Simply 126, you should ring BA to confirm, but if they say they won’t pay, then I’d ask them to point out to you in their contract of carriage where it says that customers must pay for airport transfers ticketed by the airline. If they can’t, then insist on it. If they can show you where your fare was reduced 16 quid to cover the shuttle, that would be acceptable (again, IMHO), but they won’t be able to do break it down for you like that—but even suggesting this would be as a last resort.

Please post for us how this turns out. If BA are indeed now requiring passengers to pay for their hour-long airport transfers, that the airline itself ticketed, then this is a warning that should be included with any recommendation of booking BA with flights via London.

There’s another way I just thought of to go between heathrow and gatwick which can be faster if there is alot of traffic..Grab the 285 bus to feltham station and switch to a train bound to clapham junction and switch once again to a frequently running train to gatwick..All in about 2hrs and avoids the traffic on the M25!
