First, I do think HAV is a decent airport. However the VIP lounge is very shabby, without windows. Upside is the restrooms are far better than the "public" ones and they have complimentary HC, all types. Only one daily newspaper of course.
Good thing is all airline offices is located in the same corridor right beside the CI counters (small entrance to the right of the airport tax counter), so if you face any problems at CI, come late or need to discuss an upgrade with the manager it is easy and quick to find the office and the guy.
