The new restrictions, which were announced by the French government on Thursday (16 December), are set to come into force on Saturday (18 December).
Following the announcement, Abta chief executive Mark Tanzer urged the UK government to bring forward a support package for the sector, in a bid to prevent company failures and job losses.
"The travel and tourism sector has had little chance to generate income since early 2020 and is now faced with another wave of cancellations," he added.
"Travel businesses have reported turnover at just 22% of pre-pandemic levels following two years of government-imposed restrictions and consumer confidence in overseas travel has been hit hard."
Tanzer said any government review of business support to address the impacts of Omicron must include, "as a priority", travel agents and tour operators.
Meanwhile, Clive Wratten, chief executive of the Business Travel Association (BTA), said the introduction of an "almost blanket ban" on Britons entering France was "devastating for the travel sector on both sides of the Channel".
"It is a massive step backwards for safe international travel and once again puts livelihoods and economies in peril," he continued.
He further called on the UK government to bring back financial support for the travel sector.
"The return of 80% furlough until the end of Q1 2022 for our sector would guarantee the industry’s survival and ensure we can play our part in supporting the UK economy once more," Wratten added.
Julia Simpson, president and chief of the World Travel and Tourism Council (WTTC), said the move was an "ineffective, knee-jerk" reaction by the French government.
"Banning travel to France will not stop Covid variants that are already in France," she added. "As South African scientists said, these decisions are based on hysteria not logic.
"This decision will destroy long planned family reunions and it has long term implications for a travel and tourism sector that was just beginning to recover.
"Governments should be focusing on individuals allowing people who are fully vaccinated to travel freely. Banning whole countries has been proved to not work."
