MAN-AMS will operate twice daily M-F and Sunday with a single flight on Saturday. All rotations this Summer (end of May onwards) will be operated by a MAN aircraft.
Incidentally, the 6th aircraft that will be arriving at the end of May will be an A320. Obviously things change and looking at the programme, 3xA320 and 3XA319 would do the job but A320 is what I'm being told by management.
