Virgin
Just flew down on Virgin Little Red this morning and although I'm aware no service starts with 100% loads there was only 20 passengers onboard the A320 which is a bit concerning when the comparable BA service looked 100% full. There was even a post in another thread saying there was 2 pax on one of the rotations.
Early days yet though and I'm sure bookings will pick up once people get to know about the service. I don't think there was much advertising until a few days before the inaugural which probably explains the very low loads.
Time will tell...
