It’s no secret that airlines and airplane manufacturers have been clobbered by the coronavirus pandemic.

International flights traditionally flown by jumbo jets are particularly hard hit. Borders are closed and people aren’t flying.

There is a small silver-lining. Just as restaurants started take-out service to survive, airlines are filling planes with freight.

U.S. airlines are reeling from the pandemic and have lost more than $20 billion combined in the last two quarters. Even with the surge in air freight rates, cargo revenues aren’t enough to make up for those losses on their own, especially with capacity still limited, CNBC’s Leslie Joseph reported earlier this month.

“However, it has become a more important revenue source with many passengers still forgoing flights,” Joseph reported.

Before the coronavirus, decades of a long aviation boom spawned a network of nearly 50,000 air routes that traversed the world. In less than a year, the pandemic wiped almost a third of them off the map, according to Angus Whitley of Traveller.com.

In late January, 47,756 operational routes crisscrossed the world, more than half of them in the U.S., Western Europe and Northeast Asia, according to OAG Aviation Worldwide. There were just 33,416 routes on the global schedule on Nov. 2.

For shippers, the shortage of passenger flights has a corresponding impact on air cargo. About half of the world’s air freight is flown in passenger planes’ bellies.

Even though airlines continued to rehabilitate cargo business in September, the air travel recovery from the coronavirus pandemic is stalling, Eric Kulisch, Air Cargo editor wrote. If airplanes are grounded, so is cargo. It is that simple.

Air cargo sector has retained 92% of its business, while almost 90% of passenger demand has evaporated because of travel fears and government restrictions.

Further improvement in cargo volumes could be capped by the ongoing shortage in passenger flights, even though the sliver of good news is Cathay Pacific resumed 777 flights between Hong Kong and New Zealand starting on Nov. 27.

Many carriers started taking their jumbo jets out of service before the pandemic. They parked their Boeing 747s and their Airbus A380s.

That loss of cargo capacity opened up business for companies such as Cargolux, a Luxembourg-based cargo operator with 30 747s. Cargolux is hoping that Boeing will make a freighter version of its 777X – the new composite wing aircraft.

Atlas Air Worldwide Holdings, Inc. Recently announced third quarter 2020 net income of $74.1 million, a stark contrast to second quarter losses by United Airlines ($2.4 billion) and Delta Air Lines ($2.1 billion).

Atlas leases 737 and 767 aircraft to Amazon which is expanding its fleet and plans to have 80 freighters flying by June 2021. Analysts believe Amazon’s air fleet, combined with its massive network of truck trailers and vans, could one day position it to rival UPS and FedEx.  

Amazon’s $1.5 billion air hub in northern Kentucky could help give it an edge. The hub, scheduled to open in 2021, is designed to have capacity for 100 Amazon-branded planes and handle an estimated 200 flights per day, according to a report by Annie Palmer of CNBC.

While some analysts project it may take up to five years before passenger flights return to pre-pandemic levels, air freight is steadily growing in importance.

Korean Air forecasts high demand for traditional air cargo such as semiconductors, auto parts and e-commerce supplies and believes it will benefit from urgent medical supply demands associated with Covid-19.

Its executives believe the lack of trans-oceanic container ships, opens even more opportunities for air carriers.

Hopefully, the increase in air freight will led to new airplane orders for Boeing.

That would be a shot of good news for Washington.
