Thanks Boeing 7E7 for the reply and it all seems quite positive so far, In the summer you don't get any problems then with back to back longer night sectors with duty hours. I presume at present on the 737 the longest days are the LCA & PFO sectors although I am sure SSH will be back soon. What happens with the Cape Verde flights are they a stop over sectors ?
No down route aircraft swaps are not a problem if organised correctly and not done at the last minute like on my recent flight where all the bags were loaded and then decided to do the swap or like at my previous employer do an aircraft swap with an aircraft you know is running 1hr30mins late already.
At present I am not to fussed about the long haul and Canada would be ok for a few weeks but not for the whole winter with family life.
All in it looks quite appealing I will keep my eyes open for the next recruitment drive and see what position I am in then.
