I'm a March new hire - NYC ER. Last month I flew two 4 day and two 3 day trips. Sat short call one day. Total of 77 hours for the month. I commute from PDX - one mainline flight a day, so I usually come out the day prior. I don't like to sit around the crash pad so I yellow slip as much as possible.
I have a line for October - two four day trips (GRU) a three day (AMS) and another three day that starts on the 31st. Only 65 hours so I white slipped another four day trip. Will most likely be back on reserve in November.
The nice thing about ER flying in JFK is that we have only one early morning departure (01:10 to GEO) and one mid morning departure (08:50ish to LHR) - all the rest of the SCEHDULED rotations report after noon. And all but the return from LHR get back in time for my 19:30 departure back home. On a typical day, the reserve usage is pretty predictable - and if you only have one day of reserve left, there is not much that you can be used for. There are usually a number of reserve lines that have chunks of days off (such as two 6 or 7 day chunks); that helps with the commuting. Even with my trans-con commute, I have found my QOL to be pretty good so far.
Still looking forward to that SEA and PDX ER flying though!
