International $200-300 round trips will become common

There are several low cost international airlines.

Norwegian currently flies from 15 airports in the United States to Britain, Denmark, France, Ireland, Norway, Spain and Sweden, as well as to the French Caribbean. In the coming months, the airline plans to add more than a dozen flights from the United States. Summer 2017 Norwegian is adding include Orlando, Fla., to Paris (July 31); Fort Lauderdale, Fla., to Barcelona (Aug. 22); Denver to London (Sept. 16); and Seattle to London (Sept. 17).

One recent search, from New York City to Paris, was for a departure on Oct. 6, returning on Oct. 15. A round-trip direct flight was about $561 with taxes and surcharges.

XL Airways, a French low-cost carrier, had a nonstop round-trip fare from John F. Kennedy International Airport for $471.20 on Expedia including taxes and fees. Norwegian is offering its own promotions — like round-trip, nonstop flights between New York and Paris in March 2018 for around $400.

Level, another nascent player, announced in June that it would be offering low-cost long-haul flights.

Other top ranked international low cost airlines are:

AirAsia X is the long-haul subsidiary of Malaysia’s low-cost mega airline AirAsia. The airline’s fleet of Airbus A330-300 jets are outfitted with both premium and economy cabins and operates throughout Asia.

JetStar Airways the low-cost subsidiary of Australia’s national airline — Qantas.

AirAsia Berhad is a Malaysian low-cost airline headquartered near Kuala Lumpur, Malaysia. Air Asia X has ordered 66 Airbus A330neos, an aircraft with better range and fuel efficiency than the current-generation A330-300s already in its fleet. The A330neo should be capable of flying from East Asia to the Continental United States.

Low-cost, long-haul Malaysian carrier AirAsia X began its U.S. service with introductory one-way fares starting at $99 from Honolulu to Osaka and $149 for continuing service to Kuala Lumpur.
