Commuting
Hi Piosee. Commuting is certainly possible, but you will find it hard going in the peak summer months (probably as you do now with FR).
A very typical summer roster pattern is 5/6 on, 2 off. If you finish on a late, the following day is a rest day plus 2 off which would be useful to you. You occasionally get single days off rostered. At MAN/LBA both fleets cover airport standby duties (6-7 hours, 3-6 per month), with some starting at 0500z. Typically your first day back will be one of these or, early AGP/PMI/ALC, so for the majority of the time you will have to commute to base on the eve of your 2nd day off. You will sometimes only get one whole day at home as a commuter.
As already stated, you can request a block of 3 RDOs per month, which are generally always approved. Roster disruption is minimal/nil when compared to previous operators. You probably won't commute home on all your days off so when "stuck" at base you can always make yourself available to work, which will pay for your commuting for the month.
Once through the first summer, you could opt for 80% and stay at home for 5 months over winter on paid leave. Most find a side project which more than makes up any lost net earnings (in your case saving money through no commute/local digs). Another consideration is your pay will be in GBP not euro.
