Turbulence in the budget airline industry continues to be expected. But for savvy leisure travelers looking for international flights , there are more ups than downs right now.

First, the downs. Norwegian Air threw a wrench into cheap trans-Atlantic flight options this summer by announcing the cancellation of six routes between Ireland and North America. The decision, effective Sept. 15, was blamed on the worldwide grounding of the Boeing 737 Max after two deadly crashes involving the aircraft. According to a news release, 18 of the discount carrier’s fleet were affected, making the Ireland routes “no longer commercially viable.”

Earlier this year another budget airline, WOW Air, went bankrupt. (An American company, USAerospace Associates, recently purchased its assets and will attempt to relaunch the airline, initially as a freight-only carrier.)

And yet, “it’s the golden age of cheap flights,” said Scott Keyes, who by his estimation has visited 48 countries. He co-founded Scott’s Cheap Flights, a travel site that alerts members when deals pop up.
