I noticed WN has started running some routes +/- a flight on Fridays. I hadn't seen it before up until a few weeks ago that they were running a different frequencies on different weekdays Mon-Fri (except for some holidays).
MCI-PNS daily except Friday
Interesting catch. This is actually an increase over what WN originally published when they loaded the summer schedule a few months ago. Originally, MCI-PNS was only going to be on Sat-Sun this summer (it was daily last summer). Even now, MCI-PNS on Mon-Thurs appears to be only available in June. It appears that WN is getting more nimble with more tactical additions to the schedule.
Speaking of nimble, it's amazing to see how WN's schedule will vary by day of the week at PNS.
Here's the June departure schedule for PNS:
Mon-Thurs: 2xBNA, 1xHOU, 1xMCI (Total 4 flights)
Fri: 2xBNA, 1xHOU (Total 3 flights)
Sat: 3xDAL, 2xBNA, 2xMDW, 1xDEN, 1xAUS, 1xMCI, 1xSTL, 1xHOU (Total 12 flights)
Sun: 2xBNA, 1xDEN, 1xHOU, 1xDAL, 1xMCI, 1xMDW (Total 7 flights)
Funny to see a station go from 3 flights one day to 12 flights the next. WN even has all 12 flights spaced out so that they really only need one gate on Saturdays. Only thing missing really is a BWI flight. WN seems less willing to compete with AA/DL on traffic from the Northeast/Midatlantic.
