It's not just you, the air travel experience is getting measurably worse.

Consumer research firm J.D. Power this month released its 2023 North America Airline Satisfaction Study, which measures passenger satisfaction among business and leisure travelers of major airline carriers.

For the second straight year, the study found that passenger satisfaction has declined, driven largely by rising airfare costs. It slipped 22 points between 2021 and 2022, according to J.D. Power, and seven points between 2022 and this year.

J.D. Power surveyed 7,774 passengers who traveled between March 2022 to March 2023. The airlines were scored on a 1,000-point scale and judged on seven factors:

• Check-in
• Boarding
• Baggage
• Aircraft
• Flight Crew
• In-Flight Services
• Costs &Fees

But while customer satisfaction has slipped overall, several airlines are still receiving high scores from travelers. These are J.D. Power's top airlines of 2023.

The best airlines in North America in 2023

Best in First and Business Class

1. JetBlue Airways: 893 points
2. Delta Airlines: 865 points
3. United Airlines: 848 points

JetBlue Airways ranked highest in customer satisfaction in first/business class for the second year in a row, with a score of 893.

In May, the airline announced it was adding a slew of new perks to its loyalty program, including the choice of early boarding (except for basic economy ticket holders) and priority security screening.

Delta Air Lines ranked in second place in J.D. Power's study with 865 points.

The airline is one of the oldest in the business and serves more than 1,000 destinations in over 60 countries on six continents.

Delta's premium economy class offers passengers adjustable seats with "even more legroom," an expedited airport experience, and enhanced service with a complimentary alcoholic beverage, according to its website.

JetBlue Airways came in a close second with a score of 840, which is still 20 points above the overall average score of 820 out of 1000.
