Air traffic over the weekend hit its highest level in more than a year with the return of vacationers and improved prospects for several major airlines.

The Transportation Security Administration examined more than 1.34 million people on Sunday, 86,000 more than the same day a year ago, shortly after the World Health Organization declared Covid-19 a pandemic.

That number was still 45% below 2019 levels, a sign that the aviation industry has a long way to go before it bounces back to pre-pandemic levels. But TSA screenings have exceeded 1 million every day since Thursday. achieve the best route in a year.

Airlines are becoming more optimistic. Both Delta Air Lines and JetBlue Airways announced Monday that bookings have increased this month as more people are being vaccinated.

JetBlue announced Monday that it expects earnings before interest, taxes, depreciation and amortization of minus $ 490 million to $ 540 million, better than its previous forecast of a loss of $ 525 million to $ 625 million.

Airline CEOs are likely to express some optimism about the recent rebound during a JPMorgan industry conference Monday.

JetBlue was up 5% and Delta was up more than 4% in morning trading. American Airlines and United Airlines gained more than 8%.
