BigL, yep its a big decision. I bloody enjoyed shorthaul but now that EJ and co have made that job such hard work ie 4 sectors 5-6 days on, it leaves you with no quality time at home, or time on your hands to do other things. Longhaul either cargo or pax, altho difficult in other ways, gives you this.
I'd sugget getting as informed about the job asmuch as poss and seeing if a jump to CX is worth it....goodluck
