Southwest reveals 11 routes; Denver and Atlanta get three each

Southwest has revealed 11 routes for W20, of which nine are new and two are resumptions. 

These 11 involve 16 airports across Southwest’s network of 88 US airports this coming winter.

In all, 131 weekly frequencies will be added for an average frequency of 12 per route.  This average is helped by four routes having three-daily services from the start: Long Beach to Phoenix and Louisville, Oklahoma City, and Omaha to Atlanta.  

Of Southwest’s three Atlanta additions, only Omaha is new; Louisville and Oklahoma City are resumptions.  Louisville was last served by the airline in 2014; Oklahoma City in 2016.

Most routes have only one competitor.  Only Nashville to Santa Ana will have no non-stop competition.  Last year, Nashville – Santa Ana had 59,000 local passengers, according to OAG Traffic Analyser, and connections are available across the eastern US over Nashville.

Atlanta – Louisville 17-Dec 21 Delta (58)
Atlanta – Oklahoma City 17-Dec 21 Delta (41)
Atlanta – Omaha 17-Dec 21 Delta (33)

Denver will have 68 Southwest routes this winter

Of the 16 airports involved, Denver will have by the most Southwest routes this winter: 68. Alongside Birmingham, Little Rock, and Wichita, Charlotte will also join Southwest’s Denver network on a non-stop basis from December.

Phoenix, Dallas Love, Las Vegas, and Chicago Midway will be Denver’s top routes from the Colorado capital in the week of 17 December, based on having at least 10 daily non-stop departures.

Wichita, meanwhile, will have the fewest with four routes: Denver (daily), Las Vegas (daily), Phoenix (daily), and St Louis (twice-daily).  Denver, Las Vegas, and Phoenix handle Southwest’s connections across western US destinations; St Louis across central and eastern airports.

12 destinations available from Wichita over Denver

Southwest’s new Wichita – Denver service means that 12 destinations will be available over the Colorado city on a two-way basis, OAG Connections Analyser shows, as in the map below.

This will supplement the carrier’s existing offerings to them via Las Vegas and Phoenix, growing its dominance.

These 12 are based on a maximum connecting time of four hours and a maximum circuity of 130 (i.e., no more than 30% longer than non-stops would be).

In reality, the 12  have an average waiting time of 124 minutes and average circuity of just 105.  The latter highlights Denver’s position as a connecting airport atop key traffic flows.

In all, these 12 have 335,000 passengers from Wichita, OAG Traffic Analyser indicates.

      Hi Jon. That’s correct. This was announced after the other 11 were, so didn’t make it into the article. But still: great to see! Many thanks, James.
