The four-day event, originally fixed for 30 May to 3 June, will now be held in Las Vegas over 18-22 September, 2021.
A new 10-14 May 2021 date had been set, but this has now been pushed back "to provide additional time for international long-haul travel to the US to broadly resume".
“Next year’s IPW will reunite the global travel community and be the keystone for safely rebuilding international travel to the United States,” said US Travel Association chief Roger Dow.
Dow added: “While IPW will look a bit different next year, expect it to be the turning point for the all-important inbound travel sector."
Registration for exhibitors is due to open in mid-November, followed by buyer and media registration in early-2021.
The event will be held in the newly-built West Hall of the Las Vegas Convention Center.
