Im based in the UK and live in Ireland.
You can jumpseat to and from work for free,medicals(i do mine in the UK) and sim sessions.
5 on 4 off roster.Spend 5 days in an apartment close to the airport(works out way cheaper than b and b and you save on food etc and living in your own place is nicer then b and b living) .Then i J/S straight home for off days,works out well
Because of the J/S to and from work ,the 4 days off isnt really 4 full days,maybe 3 and half with half a day travelling to work and home.
