Very regular user of Luton airport and always preferred using the airport to Stansted.
This new National Express service seems totally over priced, one way it's £15 to Luton Airport while from the same stations Victoria and Golders Green to Stansted it ranges fom £6.50 - £8.50 (advanced tickets) one way for a journey which from Golders Green station is 10 miles longer! Surely this isn't a competitive model, also worth bearing in mind the Stansted service is more regular too.
The way it's working out it will be cheaper to travel by train on first capital connect rather than use the National Express service, Luton losing out on this.
