Qualified B737 employment
If you are a qualified and reasonably current B737 PIC then there are many jobs available that pay more than double COPA's offer. Check out Jet Airways in India. If you not current then try Spice Jet in India. If you want even more money then take a look at all the offers in China. Want a better commuting schedule then look at KAL. Turkish Airlines & FlyDubai are also hiring.
If you are not qualified then take the COPA job if they will hire you.
