They assigned sims in our group based on seniority so most senior in each aircraft started 1 week after indoc and company tried to limit max waiting time to 3-4 weeks for the last group. Sim start schedules were pretty firm and indoc team was hesitant to trade start dates around based on personal situations. Sims are typically four 5-day periods (20 training days) with 2 days off in between each if sim scheduling allows. We worked right through all holidays (4th of july in my case). I positive spaced home each time for my 2 days off. Then observation rides and OE get scheduled as soon as possible after sim completion. Takes about 3 trips over 2 weeks to get this all done. Observation trip had to originate in your assigned city but OE rides could start out of another base if you requested and they had availability. I did one out of NYC and one out of SLC. You have to complete two OE trips and have the required hours. In my case I had the hours done on day 2 of second OE trip but OE is not complete until last day. Another person I know finished OE 13 min short of total hours and had to have another OE trip scheduled. Add all that up with 2 weeks of indoc and the min time is about 9-10 weeks and max is around 13 weeks. Again each aircraft has small differences and training pipeline is working at max effort. The schedulers closely manage everything to ensure you get through in a timely manner. They even hit me for my 200 hundred check on a charter trip. Line check airman's first words were "this is so nonstandard...we never do this but the schedulers needed to get it done."
