Perhaps nowhere is the world's lack of flights due to the coronavirus pandemic more clearly felt than at Dubai International Airport, for years the world's busiest for international travel.

Its Terminal 3, which sees tens of millions pass through it each year, stood empty and quiet on Wednesday, the once-full departure board showing only seven flights for the sheikhdom's long-haul carrier Emirates.

Its cavernous walkways, typically chilled to near-Arctic levels—even with being on the Arabian Peninsula—felt warm and humid in parts as worked at a slower pace. No water rushed down its fountains and some stores and restaurants stood closed.

It is for Dubai, which through Emirates succeeded in building a major tourist and shopping destination in this one-time pearl-diving village. Emirates has been laying off staff, including in large groups this week. The carrier did not offer figures for how the layoffs affected its staffing.

"Given the significant impact that the pandemic has had on our business, we simply cannot sustain excess resources and have to right size our workforce in line with our reduced operations," Emirates said in a statement.

Paul Griffiths, the CEO of Dubai Airports, previously told The Associated Press in May that without a vaccine or a permanent solution to the virus, there could be "quite a low level of activity for quite some time" for the global aviation industry.

On Wednesday, customers and staff alike wore masks and disposable gloves at the airport. Thermal heat scanners looked over passengers, counting them, warning if someone had a high temperatures or wasn't wearing a mask. Airline personnel and duty-free cashiers stood behind plexiglass barriers.

The International Air Transport Association estimated Tuesday that airlines will lose $84.3 billion this year due to the travel disruptions caused by the pandemic. While 2021 will see a rebound, the IATA predicts passenger numbers will likely only reach levels seen in 2014. Losses will drop to $15.8 billion, the group estimated.

The association acknowledged the concerns travelers still have in returning to air travel will affect the recovery of global aviation.

"Airlines are going to need to try to stimulate demand through relatively low fares," said Brian Pearce, IATA's chief economist. "A critical thing for getting passenger confidence back is confidence in the biosecurity, that flying is safe."
