Today, TripAdvisor announced the winners of its 2018 Travelers’ Choice awards for airlines, recognizing travelers’ favorite carriers around the world. This year, Singapore Airlines was named the number-one airline in the world and Southwest Airlines ranked as the best domestic carrier. Award winners were determined using an algorithm that took into account the quantity and quality of airline reviews and ratings submitted by travelers worldwide over a one-year period on TripAdvisor flights. (Note: On the domestic front, TPG’s list of best and worst airlines yielded similar results.)The 2018 award categories expanded to honor 69 airlines that provide exceptional value and service across the world in four categories: the top airlines in the world, the top airlines by geographic region, the top airlines by country, and the best airlines by class of service (first, business, premium economy, economy). Winners were based on airline reviews submitted from February 2017 to February 2018. Among the global top-10, Asian carriers prevailed with four airlines on the list (Singapore Airlines, Japan Airlines, EVA Air and Korean Air) followed by the Middle East with two airlines (Emirates and Qatar Airways).TripAdvisor’s 2018 Top Airlines in the World:According to TripAdvisor, these awards recognize airlines around the world that deliver consistently exceptional experiences to global travelers.Singapore Airlines, SingaporeAir New Zealand, New ZealandEmirates, United Arab EmiratesJapan Airlines, JapanEVA Air, TaiwanSouthwest Airlines, United StatesJet2.com, United KingdomQatar Airways, QatarAzul, BrazilKorean Air, South KoreaThe 2018 Class of Service (North America) winner is Southwest for Best Economy Class.TripAdvisor’s 2018 Top Airlines in North America:Southwest Airlines, United States (Best)Alaska Airlines, United States (Winner)Delta Air Lines, United States (Winner)Hawaiian Airlines, United States (Winner)JetBlue, United States (Winner)WestJet, Canada (Winner)TripAdvisor’s 2018 Winners for Class of Service (Globally):According to TripAdvisor, this award recognizes airlines around the world that provide a consistently exceptional passenger experience in each cabin.Best First Class: Singapore Airlines, SingaporeBest Business Class: Qatar Airways, QatarBest Premium Economy: Air New Zealand, New ZealandBest Economy: Singapore Airlines, SingaporeSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
