that is precisely why DL created economy basic fares.
DL knows full well that when fares go up high enough and WN is no longer able to provide low fares because their costs are not much lower than the legacy carriers, the ULCCs will move in.
Let's check back in a year and see how effective the ULCCs have been in penetrating ATL compared to DFW>
in the most recent quarter, the ULCCs had less than 4% of the ATL market compared to 11.5% of the DFW market.
further, ULCC share tends to come out of LCC and the weaker legacy carriers in a market than from the strongest legacy carrier. That is simply a reality of the strength of carriers in each market. NK and F9 are more likely to compete with WN than DL, esp. given that in some cases they will offer significant amounts of capacity compared to WN but far less than DL.
because there is no legacy or LCC 2nd carrier at DFW - DL is 40 share points behind AA - the dynamics are different.
and you will also be interested in knowing that DTW and DFW look more alike with the legacy carrier vs. ULCCs.
the difference is that there is no strong LCC in DTW while there is at DAL.
Delta can handle this much better than South West.
Delta has already announced plans to compete with ultra
low cost carriers. It will
be interesting to see how how South West responds.
WN's response is to give away 1/4 of its tickets.
WN's costs are not capable of supporting that level of discounting.
this is exactly why I have said that WN's level of frequencies in many markets is below what they need to defend their market share.
