Recently flew to JFK with family on Maxjet which was brilliant. Seats are near horizontal, CC excellent and meals/IFE superb. There are only 100 seats in their 767s albeit they are older a/c and can be a bit noisy on takeoff and landing. Ample room in cabin; seats in 2-2-2 formation.
That said departure from Stansted (which was very pleasant) with VIP lounge both ends. Cheaper than silverjet also.
Would happily fly with them again over the pond.
