Chose Atlantic because I needed a hangar for the extremely cold weather. Nice reception and services. Had a minor maintenance issue--required nitrogen charge for the right main strut--and it become a major issue to get maintenance support to the aircraft. Line crew was surley, front desk was helpless to assist, and I was just trying to get the aircraft returned to a flyable condition so I could depart. When I most needed customer service and support--Atlantic let me down.
