they do accept foreign LowHour FOs who buy their own TR and LT.. The question is, are these FOs kicked out after the 500 hours LT or do they stay longer till they at least break even and leave with 1500+ hrs ?
You are confusing some companies: Freebird, Atlas and Pegasus used to do LT programs. SunExpress has never done line training programs but used to have a one yearcontract to start you of with. The reason they are still hiring and training low time FO's is because a lot of foreign SXS FO's went to become FO at Turkish once they had enough hours (SXS is a joint venture between Lufthansa and Turkish airlines)
The rest is 100% like DutchExpat is saying..
