The Ryanair service from Stansted (or perhaps 'Stanstill' is a better name) currently departs at 8.00 AM From Stansted, London and from Nimes at 11.20 AM
They are also currently using a plane that is a cut above the usual Ryanair bus as it has leather seats, obviously bought by the previous owners of the craft.
The Airport itself is very small, and only seems to operate a couple of other routes withing France itself.
If you are arriving on the Stansted flight by Ryanair, then be warned that you could have quite a wait for car hire.
The problem is that many Ryanair customers use the Ryanair site to book with Hertz - so their desk is packed whilst the others stand deserted.
If you are travelling as a couple then it might be useful for one to wait for the luggage whilst the other gets to the front of the queue - or just book your car hire with one of the other companies.
