If you tend to travel internationally, there's a report you may want to check out. According to a new study of the best and worst airlines in the world, Canada's largest airline, Air Canada ranks as one of the worst airlines in the world for long trips.

Released on December 4, the Airline International Destination Satisfaction Study was based on nine key factors: in-flight services, cost and fees, aircraft, flight crew, check-in, boarding, immigration, baggage, and reservation.

Based on responses from 6,287 passengers from September 2019 to October 2019, Air Canada has been ranked amongst the lowest international airlines in the J.D Power study.

According to the overall customer satisfaction index ranking for Asia, the Canadian airline was ranked in 10th place out of 12 airlines.

The study measures passenger satisfaction with certain airlines that fly from North America to Europe and from North America to Asia.

In terms of European destinations, Air Canada landed in second to last, at 11 out of 12, right before Norweigan Air Shuttle.

However, just last summer, Air Canada was named North America's best airline for the second time.

Yet, the report found that cost and fees seem to be less important than in-flight services when it comes to satisfying passengers on their international flights.

It differs if you travel within North America. The study found that passenger satisfaction is only partially linked to an airline's cost and fees.

Although, passenger satisfaction has been an issue in the past as a Quebec woman was banned from flying with Air Canada after getting kicked off a plane.

Back in June, people even threatened to boycott Air Canada after a racist incident towards one of their passengers from another flyer.

“A low fare may be the best way to attract a first-time international passenger,” said Michael Taylor, Travel Intelligence Lead at J.D. Power, in the study.

“But retaining passengers on routes to Europe and Asia is all about delighting customers with great in-flight experiences," he continued.

The highest rank for travel from North America to Europe was given to Turkish Airlines. For airline travel to Asia from North America, Japan Airlines came in first.

In response to the rankings, the Canadian airline told Narcity that "Air Canada has been ranked Best Airline in North America by Skytrax for three consecutive years and in eight of the last 10 years. In its evaluation, Skytrax undertakes an extensive annual survey of more than 21 million air travellers versus 6,287 by J.D. Power.

"In addition, Air Canada receives consistent recognition for its products and services in the form of a wide range of other awards, most recently being named Airline of the Year by Global Traveler on December 2, 2019," they continued.
