Italian carrier MyAir claims to be evaluating proposals from investors, as the airline faces serious operational problems at one of its main bases.
The country's civil aviation authority, ENAC, has suspended MyAir flights from Bergamo's Orio al Serio Airport.
Orio Al Serio's managing authority, SACBO, says it requested the suspension because of "violation of obligations" over payment of "taxes, duties and tariffs".
Bergamo is an important operations centre for MyAir, but the carrier has removed it from the booking page of its Internet site.
It is unclear whether any of MyAir's aircraft are still at Orio Al Serio Airport.
ENAC and MyAir decline to comment further on the matter at present, but the airline has issued an update on its financial situation claiming that it is "evaluating proposals" made by investors as it bids to recapitalise.
Owing to the precariousness of its finances, the airline is operating on a temporary licence issued by Italian civil aviation authority ENAC, which has voiced concern over MyAir's performance.
MyAir operates Airbus A320 and Bombardier CRJ900 aircraft. The carrier is one of the launch customers for the CRJ1000, with 15 on order.
It has a marketing partnership with the struggling Central European budget carrier SkyEurope Airlines.
