I fly for a UK charter airline and compared to other UK charter airlines we are pretty similar. There are no typical routes which is one of the nicer points, we boast about 50 destinations from my base airport (LGW) alone. Some of these destinations are only served once a week but most are served more frequently.
In the Summer (May - Oct) we fly around 90-95 hours a month which is hard work. The winter (Nov - Apr) is quieter and typically we fly 50 hours a month, sometimes less. November is usually very quiet as the ski season hasn't started and the Summer program is finished.
The vast majority of our flights are "there and backs" which makes life pretty easy (home at the end of every duty typically). So a standard duty will involve an outbound and return flight, each sector ranging from 2 hours to 5 hours depending on the destination. Worst duties are Paphos / Larnacas taking about 4.5 / 5 hours each way. So a 6am report @ LGW with a 7am departure to Larnaca will get you back into LGW for about 6pm which is 12 hours on duty.
We don't have the luxury of the US-style duty regs on maximum 8 hour 2-crew duty either so that 12 hours is just a single crew (two of us). It is worse at night, reporting 6pm and returning for 6am
. Quite a large proportion of our flights are through the night.
As for rosters we get ours roughly on the 15th of the month prior to the applicable month (so on or around 15th Sep I should get my 1st to 31st October roster). Don't get a say in when or where I fly as I am not very senior, but of course guaranteed to not be working any booked holiday time.
Getting called out from standby is quite common over the Summer, probably 1 in every 3 times on average. Less common in Winter though. My airline likes to use standby duties as a way to reorganise your entire month which is a bit awkward on your social life.
On the plus side we also get the occasional longhaul (763) flight to the Caribbean / Mexico / Florida and normally get at least a few days off at the destination, sometimes up to a week which is very nice indeed
Hope this was of some interest?
I used to love the smell of Jet-A in the morning...
