AIRLINES’ GUESS at '21 losses raised to $48B.

The airline industry’s chief lobby group widened its estimate for losses this year by about a quarter, saying new covid-19 flare-ups and mutations have pushed back the timeline for a restart of global air travel.

Carriers will lose about $48 billion in 2021, the International Air Transport Association said Wednesday in an online presentation. It had earlier forecast a $38 billion deficit.

“This crisis is longer and deeper than anyone could have expected,” said Willie Walsh, the former chief of British Airways owner International Consolidated Airlines Group, who’s now the transport association’s director general. “Losses will be reduced from 2020, but the pain of the crisis increases.”

The downward pivot comes as airlines contend with new travel bans and restrictions arising from outbreaks in large aviation markets such as India and Brazil. Governments of countries that have ramped up vaccinations most quickly have become cautious about restarting travel to prevent the import of new variants that could prove resistant to jabs.

This week, the U.S. State Department said it would declare about 80% of the world’s nations no-go zones. In Europe, the United Kingdom has held off on confirming a plan to restart travel in mid-May, saying it will decide closer to the date. While some countries are starting to open up to vaccinated tourists, progress toward so-called vaccine passports has proven slow and complex.

After the industry lost about $126 billion in the teeth of the crisis during 2020, there were high hopes for a rebound in air travel during the first half of this year. The association now says the crucial summer season is at risk.

Demand will reach 43% of 2019 levels during 2021 — a more optimistic outlook than issued in February, but less bullish than in December, when vaccines were first being rolled out. At that time the association saw traffic this year recovering to about half of prepandemic levels.

In the U.S., investors have soured on the chance of a quick recovery in aviation, sending a Standard & Poor’s index of major airlines to 10 straight days of declines this month, the longest streak since at least 1989. In Europe, trans-Atlantic specialist Virgin Atlantic Airways Ltd. said Wednesday that it won’t get its fleet fully back in the air until October or November.
