I second SB1089. I've been a member of Ravenair for 18 months now and have nothing negative at all to say about them. Friendliness is high on the agenda and Liverpool is very user friendly to GA flying and ATC is helpful, managing to balance GA with commercial smoothly and fairly. (Ravenair moved from Manchester for this reason!)Aircraft availability (PA38s and Senecas/Aztecs)is good.
