Many of the lowest fares came from regional and secondary airports rather than the country's largest hubs. That's partly because smaller airports operate a little differently, with lower costs, fewer delays, and more low-cost carrier routes. They're also less likely to see the sharp price jumps that hit major hubs as flights fill up, which helps keep fares steadier-even during busy travel periods.
In 2019, WOW Air, known for its low-cost flights from the U.S. to Iceland (and from Iceland to the rest of Europe), abruptly ceased operations, leaving plenty of passengers around the world stranded. This week might bring with it a sense of deja vu, as an airline founded by several WOW alumni - PLAY, which took a similar approach to low-cost international travel - has also announced that it's flown its last flight.
