well i work for TFLy and like all the other posts its a sorted place. The ability to decline a change outside the 2 hours block window means you can plan a social life. Roster a month in advance and stable. The money is good, the pension has wobbled in the past but teh smart momney says its stable. However if you are a high hour F/O you may be waiting a long time for a 737 command esp with the merger of some very senior F/O from First Choice. Thats the only fly in the ointment, some F/O's are doing 2 days poss 3 a month and they have the best painted houses in the north of england.
Howevere as someone else stated teh godo places are the places with a stong BALPA union its worth a thought. If you want a quick command and a pot of cash then go orange at TFLY you join for the long term and teh seniority list is King/Queen.
The people are all smiley and very rarely do you ever hear anyone moan in a crew room about the T's and C's that tells me a lot ...
a happy Tflyer
