National Express bus. You can buy a ticket in advance or when u r there. Usually takes one hour. Buses (coaches) leave every 30 minutes. I have done this journey LOADS.

keeping in mind that on the gatwick end it's a major bunfight to get on the bus, and a few times I've had to wait for another bus to come along.
It's a horridly unorganised affair at LGW, with typical national suppress (ops, sorry, express) level of customer service...

Yes, but if you buy a ticket online in advance.....

We used to live pretty close to Gatwick Airport (Creepy Crawley) and a taxi to Heathrow would have cost us about fifty-sixty quid (from memory). Check out the National Express website, they do airport transfers.

Hope this helps;

Thanks to everybody for their tips and info.
So far I think my husband will want to use a taxi, it is a business or better said trip for a job interview, so expenses will be paid.

At 6am the trip could be done in 45 minutes, more likely an hour or so.
