The summer travel season is waning, lowering airfares and raising questions about demand in the coming weeks, when business travel would normally pick up again.

The Transportation Security Administration screened nearly 1.35 million people Tuesday, the lowest number since May 11. Travel demand typically plummets in late summer when the kids return to school, but Frontier, Southwest, American and Spirit airlines warned last month that they would miss out on revenue or earnings forecasts due to weaker bookings, a trend they anticipate rising cases across the Delta -Reduced variant of Covid-19.

The director of the Centers for Disease Control and Prevention, Dr. Rochelle Walensky, Tuesday advised unvaccinated people against traveling during Labor Day weekend.

According to a report by Deutsche Bank, domestic fares for most US airlines fell for the week ending August 27 compared to the previous week. The tariffs vary greatly depending on the airline and network.

For fares purchased 21 days in advance, average domestic fares for a one-way weekly trip decreased by up to 30.6% to $ 51 and $ 183 for Spirit and JetBlue, respectively.

Average US domestic one-way fares fell nearly 23% to $ 158, Delta’s more than 20% to $ 150, and United’s more than 25% to $ 199.

United announced on Wednesday that it is expected to fly 2 million passengers between September 2 and September 7, including Labor Day weekend, about three times as many as last year but fewer than the 2.6 million people that it promoted on the bank holiday weekend in 2019.
