Ryanair has been conducting a tireless crackdown on passengers who try to take bags larger than the stated maximum dimensions on to its aircraft for free. According to CEO Michael O'Leary, the number of passengers with oversized bags has gone way down since the implementation of these strict measures.
Why would this be cheaper than booking a direct flight? "Airlines make more money off pricing by market as opposed to distance," Aktarer Zaman, who created the site Skiplagged in 2013 to help travelers find these fares, tells Condé Nast Traveler. The savings can be significant; according to Zaman, travelers who use Skiplagged save an average of 47%, or about $180 per flight.
