I too have moved up about 100 places on the seniority list!
I must be one of the few who has had second thoughts about leaving!
I had the offer of F/O position on a 737 with another well known carrier (type rating to be paid for by them with a 3 year bond), but decided to stay with Bacon/Flybe after being offered a command on the Emb 145.
What swung it for me is that your pay is "red ringed" when the time comes to be transfered to a turboprop.
