Portuguese airline TAP is not only one of the worst airlines in the world (9th), but is by far the most complained about airline in the first half of the year, with 1,530 complaints made between January and June 2021. Almost twice the number when compared to the second most complained about airline, Air India, which registered 842 complaints.

This data, which is the result of a study by Bounce, analysed passenger experiences, taking into account factors such as staff service, meals, seat comfort, inflight entertainment and maximum baggage allowance, in order to reveal the best and worst airlines in the world, according to a note sent to The Portugal News.

Even worse is the low-cost airline Viva Air Colombia, which was named the worst airline in the world. This airline scores one in five in all study criteria due to the fact that few amenities are offered to customers for free. However, this airline received the lowest number of complaints, according to the study.

Next, VivaAerobus ranks second, scoring one out of five in the index for both inflight entertainment and meals and two out of five for staff service. “This could be due to its buy-on-board programme where food and drink have to be purchased”, reads the note.

Then, it is Volaris Airlines that is ranked in third place, “mainly due to the airline discontinuing inflight entertainment in 2019, it has one of the lowest scores in our index, and with a low maximum baggage weight allowance of 10kg, this carrier ranks as the third-worst airline”. Volaris Airlines is followed by Ryanair (4th), Interjet (5th), Vueling (6th), EasyJet (7th), Ukraine International Airlines (8th), TAP (9th) and Gol Airlines (10th).

On the other hand, the study also revealed the five best international airlines around the world with Ana All Nippon Airways named as the best airline in the world.

Ana All Nippon Airways “is the largest airline in Japan by both revenue and passenger numbers. It ranks the highest in customer-rated staff service, the only airline in our list to score full marks in our airline index for this factor”. In addition, this airline only received 34 complaints, a low number comparing to the competing companies.

The Japanese airline is followed by Singapore Airlines in the second place and Korean Airlines in third. Please, have a look at the full research here.
