Estonian carrier Nordica has suspended operations carried out from Tallinn under its own brand, owing to cost pressures.
The carrier is blaming competition and overcapacity on Tallinn routes for its decision.
Nordica says the situation is preventing the carrier from operating profitably. It stopped its own-brand services on 27 October.
But it states that it will remain active in air transport, turning its attention to charter flights and participation in public tenders.
The airline had indicated earlier this year that it would back away from flying under its own commercial risk from the winter season.
This risk will instead be transferred to its partner, Polish flag carrier LOT, which will maintain flights from Tallinn to Stockholm, Brussels and Warsaw.
Nordica is cutting five unprofitable routes from its network "until an improvement in the competitive situation is seen". LOT will handle routes and ticket sales.
Its capacity provider Regional Jet, jointly owned with LOT, will continue to provide air services to LOT, SAS and other contract partners.
Regional Jet operates 19 aircraft – comprising 12 Bombardier CRJs and seven ATR 72s – and is set to add 10 more aircraft over the next year. The carrier says it expects to introduce Embraer E-Jets.
