Flyer Talk Friends.
My family and I plan to arrive at LGW from BCN on Easyjet, arriving at 12noon. We have a connecting flight back to the US that leaves LHR on ba at 4:25pm to LAS, in First Class.

I have planned a private transfer with BA's preferred service from LGW to LHR.

I assume we will have to go through customs/immigration at LGW.

Is 4.5 hours enough time from touchdown at LGW to takeoff at LHR?
This is for a Friday in late June 2012.

Thank you for your expert advice..

BTW..being from San Diego, I have now taken the new BA service to LHR return and it's fantastic in CW. Great service and beats any US airline to Europe bar none.
