The countryB次元官网网址檚 two largest airlines are ending their on-board seat distancing policies starting July 1, raising health concerns amid a pandemic that has devastated the travel industry.

Air Canada has blocked the sale of adjacent seats in economy class, and WestJet has done the same throughout the entire plane, to help prevent the spread of COVID-19.

The carriers said Friday they will revert to health recommendations from the United NationB次元官网网址檚 aviation agency and the International International Air Transport Association (IATA) trade group.

American Airlines also announced Friday that it will start booking flights to full capacity starting next Wednesday.

IATA called last month for an end to in-flight physical distancing rules, proposing a range of measures including some that run counter to federal government policies.

Transport Canada listed physical distancing among the B次元官网网址渒ey pointsB次元官网网址� in preventing the spread of the virus as part of a guide issued to the aviation industry in April.

B次元官网网址淥perators should develop guidance for spacing passengers aboard aircraft when possible to optimize social distancing,B次元官网网址� the document states.

Some health experts have highlighted the risks of spreading COVID in crowded airports and packed cabins.

B次元官网网址淥nce itB次元官网网址檚 in the cabin, itB次元官网网址檚 difficult to stop air moving around,B次元官网网址� said Tim Sly, an epidemiologist and professor emeritus at Ryerson UniversityB次元官网网址檚 School of Public Health.

However Joseph Allen, director of the Harvard public health schoolB次元官网网址檚 Healthy Buildings program, said the HEPA air filters used on most planes effectively control airborne bacteria and viruses.

In line with federal directives, Air Canada and WestJet conduct pre-boarding temperature checks and require masks on board. They have also implemented enhanced aircraft cleaning and scaled back their in-flight service in late March, cutting out hot drinks, hot meals and fresh food.

B次元官网网址淭he new measures will continue to build on the recommendations of ICAO (the UNB次元官网网址檚 International Civil Aviation Organization) and others that a multi-layered strategy to COVID-19 safety is most effective,B次元官网网址� Air Canada spokesman Peter Fitzpatrick said in an email.

WestJet said its online booking will return to normal on Wednesday.

B次元官网网址淢oving forward, our cabin crew are able to assist should there be space to accommodate and we encourage guests to discuss seating arrangements with them once onboard,B次元官网网址� said spokeswoman Morgan Bell.

Canadians are beginning to brave air travel again as confinement measures lift, though Manitoba and the Maritimes still have strong restrictions on interprovincial travel in place while other provinces discourage it.

Swoop, a budget airline owned by WestJet, added eight weekly flights in June with 12 more coming in July after the carrier cut capacity to a single line of flight per day B次元官网网址� Halifax-Hamilton-Edmonton-Abbotsford and back.

B次元官网网址淲eB次元官网网址檙e in this minus 95 per cent mode right now,B次元官网网址� Swoop president Charles Duncan said in an interview. B次元官网网址淚t doesnB次元官网网址檛 get much worse than this.B次元官网网址�

Hope is on the horizon, however.

B次元官网网址淎t the height of it, it was common to have under 20 people on a plane. But from Vancouver just now I brought in 65. Earlier in the day from Edmonton to Vancouver we had over 100,B次元官网网址� said WestJet flight attendant Chris Rauenbusch, president of CUPE Local 4070.
