>>>When are -300s to start getting winglets?
There are no plans to install winglets on the -300s (or -500s). The -300s and -500s typically operate the shorter flights, and the payback from winglets is less as a result.
>>>I know that WN
doesnt schedule their aircraft for any particular airport, but based on the scarcity, do the 700's with the winglets tend to operate the longer flights and hence would operate from the larger bases, IE LAS
The winglet-equipped -700s do tend to operate more long-haul flights, but only because -all- -700s do. Roughly half of the -700 fleet now has winglets, and at the rate the installations are being accomplished, it won't be all that long before all -700s have them.
There are alot of things considered in aircraft routings, none the least of which is where the aircraft starts its day, and ends it day. At the end of each day, there are a certain percentage of aircraft that need overnight MX
checks/work, and those are the ones routed into overnight spots with MX
capabilities. The changes that occur to these planned routings during the day (due to aircraft UNEXPECTEDLY being out of service) are more important considerations, overall, than routing a winglet/non-winglet aircraft on a specific flight. Oh, sure, they will if they can, but the higher priority is the overnight MX
consideration. Pretty soon, it'll be a moot point...
