OO-AOG
Acrobat is used at both Monarch and Excel Air
and has consistantly been praised for many a year. It also comes at a more attractive price than AIMS and RM Rocade.
RM and AIMS feature amongst many charter, scheduled and freight Airlines in the UK, probably a 50% split. Most Airlines seem happy with the above, although not to the extent of Arcobat! (and i dont work for Mon)
Last and most important mention is that any systems are only as good as the users!!.
