pptp,

Thanks for the info. One quick clarification...pilots do actually bid lines that involve different subtypes of the 737 (and get paid more for those segments that are on the 738/739), as opposed to having separate bids for the higher/lower paying 737 types?



I know the rest requirements are controversial, and opening that can of worms was not the intent of my question! That's why I tried to frame it in terms of the airplane...I was just curious about how long the planes have to sit overnight in order to allow the crew rest when its the only plane of a given type RON at a given airport.


Another question for someone in the know...
It appears that the layout and interior of the 739 and 739ER are identical, but Boeing indicates that the -900ER has additional exit doors compared to the non-ER version. Are those optional, and CO, with a relatively low-density layout, did not need them? I have not flown on these planes so I can only go by pictures and seat maps.
