Revealed: The three most complained-about US airlines

Complaints against US airlines rose by nearly 29% in 2023, but not all carriers came in for the same level of passenger discontent. The three airlines with the highest ratio of complaints to passengers were jetBlue, Spirit, and the most-complained-about airline, Frontier, according to a US Public Interest Research Group analysis of US Department of Transportation data. Frontier had 33 complaints for every 100,000 passengers, while Spirit had 15 and jetBlue received 13. At the other end of the spectrum, Alaska received the fewest complaints, with just two per 100,000 passengers. "We have been disappointed in our historical complaints but are pleased to have seen a recent drop in complaints due to better operational reliability, the reopening of our call center, and the recent launch of the New Frontier which offers clear, upfront low-cost pricing, and no change fees," Frontier told CBS News. The Independent has contacted jetBlue and Spirit Airlines for comment. Complaints about airlines, according to the PIRG analysis, are increasing faster than the level of passengers. They rose nearly three times faster than the 11% increase in passengers between 2022 and 2023, on the way to setting an overall record of 61,233 complaints last year.<br/>
