Airlines have 'no fall-back' if EU talks fail
There is no "fall-back option" for airlines if the UK is unable to secure an aviation agreement during Brexit negotiations, travel trade organisation Abta has warned.
It claimed it is "critical" that existing deals are replaced or retained otherwise there could be a "hugely damaging" reduction in flights.
All of the UK's airline routes to the EU and the US are secured through EU agreements.
The UK could be forced to trade under World Trade Organisation tariffs if no divorce deal can be reached, but Abta has published a report warning that this would not apply to the aviation sector.
"There is no international fall-back option, such as World Trade Organisation rules, that exists for the aviation sector," it said.
"A reduction in the number of routes would be hugely damaging for holidaymakers, business travellers and visitors to the UK."
Before last year's referendum, Abta warned that foreign trips are "likely to become more expensive" if the UK withdraws from the EU.
