Hummingbird Helicopters disposed of the Mi-8s some years ago -- they are now known as Trans Maldivian Airways (www.tma.com.mv) and operate DHC-6
Also in the Maldives there was Seagull Airways -- which also operated Mi-8s.
The Mi-8 was quite popular in the atolls, but this changed after a crash in 1994, and the government decreed a couple of years later that the Mi-8 was no longer allowed to fly in the country.
Other helicopter airlines include:
Malta Air Charter -- Mi-8 -- flies sked between MLA
Baltic Airlines - Mi-8 -- flies tourist flights around SPB, with talk of scheduled services to nearby cities in future
Utair -- formerly Tyumenaviatrans - Mi-8, Mi-6, Mi-10, Mi-26 - world's largest civilian helicopter operator with over 180 operational choppers in the fleet
