The International Air Transport Association (IATA), who is considered the top industry body for air travel world wide, said that international travel is unlikely to be widespread until 2023.

Some international trips may resume next year, but most probably for professional or essential reasons, as quarantine measures and closed borers make travel for recreational purpose impractical.
International travel at the same levels as 2019 is highly unlikely until a vaccine can be produced and administered. Even after a vaccine is widely available, trust in international travel is going to take years to rehabilitate, according to the IATA, meaning airlines will be forced to charter fewer planes.
