Sorry for the delayed response folks, I've been flying non-stop since I got back to work at the beginning of the month.
I really want to move to the US ASAP (got to wait for my green card application to be complete, so probably not until June at the moment). For the time being I'm on a 23 on 10 off roster with a small turboprop airline in the Caribbean. The money is the same as it would be at a regional, but the pull of actually being able to live with my wife (hopefully in ORD), and moving on to an RJ as opposed to a 25 year old turboprop, means that I am leaning towards making the plunge.
My only two concerns are firstly actually getting a job with someone like Eagle in the summer with 1,400TT, 1050 Turbine, 100 PIC, 250 IMC but no internal rec. And secondly getting enough time off each month to be able to make it back to the UK to look after my mother for three or four days.
I really appreciate everyone's help!
