Passenger Focus, the UK’s national rail watchdog, released a survey covering spring 2008 which showed that Gatwick Express and Heathrow Express both achieved satisfaction scores above 90 per cent.
The picture was not as positive for long-distance operators, however, with Passenger Focus describing the scores awarded to Cross Country, East Midlands, First TransPennine Express, National Express East Coast and Virgin as "worrying".
Although 83 per cent of passengers said they were happy with these companies’ services, overall satisfaction scores had dropped by four per cent.
Passenger Focus chief executive Anthony Smith said: "Satisfaction with station and train facilities from long-distance operators dropped across the board and the five operators should see these scores as a red alert.
"Likewise, the value for money offered by all train companies remains a primary concern for more than half of the passengers we surveyed."
People flying from Gatwick or Heathrow can catch Express train services to the airports from Victoria and Paddington stations respectively.
