The agencies have not stopped 'lining up' (whatever that is!) for the summer season, there are many vacancies still available, B737, B767 etc.
Please don't compare all scenario's to India, such is the Indian culture they will play agencies off against each other to get the cheapest, well below the market, rates.
With regards to Sigmir, they were advertising USD7,000 + extra's a month for ATR Training Captains in India. They didn't have the contract, they didn't have that rate approved and infact it was apporox USD1,500 per month over what the airline were prepared to pay.
Sigmir are new to the 'pilot' market and one guesses that they are attempting to build up their database by advertising contracts, at inflated salaries, that they do not have!
