As of 2025, I've found only a single reported case of an alleged ban taking place:
A teenager, detained following a "skip lagging" incident earlier this
month has now been banned from flying with American Airlines for three
years, according to his family.
The purchased flight for Hunter Parsons' 17-year-old son was from
Gainesville, Florida to New York City with a layover in Charlotte,
North Carolina. The plan was for the teen to get off the plane in
Charlotte, where he lives, and not continue to New York City.
Parsons told Nexstar's WJZY his family has used skip lagging resource
Skip Lagged for the past few years, but noted he never would have put
his son in this predicament if he knew what would happen.
I say 'allegedly' because no concrete evidence was ever provided to verify this incident, nor did American Airlines officially confirm the ban. However, since there's no evidence proving the teenager was subsequently permitted to fly with AA, we can reasonably assume the report is accurate.
Additionally, several travelers have reported receiving warnings about potential bans for skipping connecting flights, such as this Reddit user:
I just wanted to give everyone some information on what not to do. I used a hidden city flight website to book my AA ticket at a lower price. I attempted to check in online before my flight, but I was presented with an error message. I came to the boarding check-in, and they informed me that if I didn't reach my final destination, I would be banned from the airline.
It's important to note that this user never confirmed an actual ban was implemented — this was merely a verbal warning without any reported official follow-up. Such warnings likely represent empty threats from check-in personnel, given the lack of subsequently reported "You are banned!" emails. Confirmed bans remain extremely rare, which is why I personally wouldn't hesitate to continue employing the "hidden city" trick if it offered significant cost savings on my itineraries.
In related news, in October 2024, American Airlines won their lawsuit against Skiplagged:
On October 15, a jury awarded American Airlines $9.4 million in
damages from an August 2023 lawsuit filed against Skiplagged — a
website airlines hate because it makes it easier for customers to book
"hidden-city" fares, also known as "throwaway ticketing," to save
money. The practice is not illegal but directly contradicts airlines'
terms of service.
Specifically, the company was ordered to pay American $4.7 million for
a copyright infringement for using American's logo on its website and
another $4.7 million for repayment of "ill-gotten" revenue.
While the payment is a hit to Skiplagged, which has 20 employees, the
website can still conduct business as usual, minus American's logo,
CEO Aktarer Zaman told Business Insider.
As promised by their CEO, Skiplagged continues to operate as of March 2025 and even suggests the very same 'hidden city' fare that got the 17-year-old mentioned above banned from AA :-)
