Remember the Pepsi versus Coca-Cola ad wars? An advertising feud broke out between 
Indeed, both airlines are major players in Denver. 
“More Flights Southwest Than…”
This time, United Airlines put up a billboard saying that it has “more flights southwest than, well, you know…” In response, Southwest Airlines placed a billboard above it that read, “Can’t hear you from up here.” Southwest also added, “Flying southwest doesn’t make you Southwest.”
Southwest Airlines added that it was ranked first in economy/basic class customer satisfaction by J.D. Power and included the line, “Don’t let the mic hit you.” Southwest has actually earned this award for the fourth consecutive year, according to the survey. On a third billboard, placed nearby to the right, United Airlines promoted its nonstop destinations from Denver, including Santa Fe, Honolulu, Tokyo, Cabo San Lucas, St. George, Kauai, Kona, Maui, and more.
The Banter Has Happened Before
The banter between United and Southwest has happened before. In 2023, Southwest Airlines’ ads around the airport stated that Southwest Airlines is Denver’s most-flown airline. The problem with the ad was that on the bottom left, there was a disclaimer in fine print. The disclaimer stated that their position is based on data from the Department of Transportation from 2010-2021.
Southwest did not include the 2022 data, which would have challenged its claim. According to Denver International Airport’s 2022 investor relations report, United carried 14,028,146 origin and destination passengers, compared to Southwest’s 12,705,505.
United, unhappy with Southwest’s ad, launched its own campaign. The Chicago-based airline posted a video on Twitter earlier today, opening with the line, “Denver’s most flown airline.” The video also featured United’s “legal disclaimer” in large text, emphasizing that it has nothing to hide and, according to the DOT, carried more passengers to and from Denver than any other airline in 2022.
