Thank you for the stats! So WN increased passengers carried already as the largest marketshare leader at almost 5.6 MILLIONS passengers just for December alone. And Delta increased their marketshare by carrying almost 2.1 million passengers in December. Yes, Delta is going to open a hub in AUS with the A220 and displace WN in a market where WN has decades of loyalty and Delta has mostly “spoke” flights to its hubs.
There is still significant demand for WN service out of RDU and SEA, even though now DL has a focus city at RDU and a hub at SEA. WN also still carries more passengers per year out of SEA than it does out of most of the other DL hub airports.
Here is the number of domestic passengers per year that WN carries out of DL hub and focus city airports:
ATL - 9,789,000 passengers per year
LAX - 9,679,000 passengers per year
SEA - 3,141,000 passengers per year
BOS - 2,899,000 passengers per year
LGA - 2,733,000 passengers per year
SLC - 2,520,000 passengers per year
RDU - 2,463,000 passengers per year
MSP - 1,948,000 passengers per year
DTW - 1,630,000 passengers per year
CVG - 562,000 passengers per year
JFK - not served by WN
There would likely be more demand for WN service out of AUS than out of any of DL's current hub or focus cities except for ATL and LAX if DL establishes a hub or focus city at AUS.
