With the aviation industry in a facing rough weather, private air-carrier Jet Airways has terminated services of up to 35 expatriate pilots who captain the airlines' Boeing 737-aircraft.

"Services of 35 expatriate pilots have been terminated by the airline," a source close to the development said on Saturday.

Confirming the development, a Jet Airways spokesperson said some 25-odd pilots have been sacked. But aviation industry sources claimed that services of up to 35 expatriate Boeing-737 captains have been terminated by the Naresh Goyal-led domestic airline.

The expatriates get between $15,000-18,000 salary per month besides prerequisites such as five-star hotel accommodation and business-class conveyance to their home country.

Earlier, Jet had sacked around 400 support staff, but later rescinded its move by taking back all the retrenched employees.

Vijay Mallya-run Kingfisher Airlines in October had announced a 90 per cent cut in the salaries of its trainee pilots as part of its cost-cutting measures.
