Airline reservations to the United States took off immediately after the White House announced the country would reopen to all vaccinated international voyagers starting next week, compelling a welcome — if challenging — industry pivot.

The long-awaited US move to welcome back international travellers — which takes effect Monday — follows 18 months of restrictions for 33 countries during the worst of the coronavirus pandemic that separated families, impeded business travel and frustrated tourists.

Big carriers including Air France, United Airlines and Singapore Airlines are scrambling to meet the sudden surge in demand, adding flights, swapping in bigger planes for smaller ones and redoubling efforts to hire and retain staff.

Just after the White House announcement, British Airways saw a 900 per cent jump in searches for flights and holiday packages to key US destinations compared with the week before.

The day after the announcement, American Airlines garnered a 66 per cent jump in flight reservations to Britain, 40 per cent to Europe and 74 per cent to Brazil.

Competition for seats on November 8 itself was especially intense, as Evelyne and Jean-Michel Desobeau discovered when they booked a trip using frequent flyer miles.

The couple, anxious to see their daughter and son-in-law, had reserved a flight from France to New York for November 2, based on a guess of when the travel ban would be lifted.

But when the date was officially set at November 8, the couple discovered that flying that day would have meant using three times as many miles as the original trip. In the end, they will arrive on November 9, using a more moderate amount of miles.

More seats, bigger planes 

At Air France, traffic has been gradually returning and “won’t change overnight on November 8,” said a spokesperson for the carrier.

The French airline has for months flown jets with empty seats. But with demand rising, it recently increased the number of daily flights between New York and Paris from three to five. 

For its Houston-Paris trip, Air France is shifting out the Airbus 330 in favour of the Boeing 777, which has more seats. The carrier expects its capacity in terms of US travel to reach 90 per cent of its pre-Covid 19 level in March 2022, up from 65 per cent in October.

Airlines are planning for a modest pullback in January and February after a strong holiday season, but anticipate strong demand in the spring that will intensify in the summer, traditionally the busiest season.

At United Airlines, traffic to Latin America has fully returned to its level from 2019, but the rest of international travel remains at only about 63 per cent.

The US carrier is betting big on a vibrant return to international travel, introducing five new destinations in the spring including in Spain and Norway, adding flights for popular destinations such as Rome and Dublin and reviving service to Frankfurt, Nice and other cities.

Too few workers? 

The industry also expects a strong, but slower, recovery in travel to Asia. 

Singapore Airlines, which benefited from a recent decision by Singaporean authorities to allow quarantine-free travel for a far broader range of travellers from the United States and Canada, anticipates flight frequency from North America to Singapore in December will reach 77 per cent of pre-Covid levels, thanks to the reopening of voyages to Seattle and Vancouver, and for trips like Singapore-Frankfurt-New York.

Burkett Huey, an analyst at Morningstar, said airlines should have enough planes to meet rising demand. But whether there is sufficient staff is “a question mark,” he said.

Airlines welcomed the exodus of thousands of employees early in the pandemic. But both American and Southwest have in recent weeks cancelled thousands of flights due in part to meagre staff levels.

Still unclear is the timetable for a robust recovery in business travel, an unknown that affects airline planning.

Traditionally, airlines fly wide body planes across the Atlantic on busy routes to provide comfortable seats for business travellers, and then organize smaller planes for touristic destinations.

But if business travellers are late to come back, airlines could decide to plan more direct flights using the newer narrow body jets with longer range.
