Some countries have lifted the blanket travel ban, such as the Netherlands, which now requires a negative coronavirus test from travellers instead.
Greece and Cyprus require a negative coronavirus test before arrival, as well as two in the country during quarantine.
While experts do not believe the new variant of the virus -- one of several -- is more lethal or will affect the impact of vaccines, it may be up to 70 percent more transmissible, according to early data from the UK.
A German government source said restrictions on air travel from Britain could be adopted by the entire 27-member EU and that countries were also discussing a joint response over sea, road and rail links.
However, the EU Commission has urged the UK travel bans to stop, saying in a statement: "Flight and train bans should be discontinued given the need to ensure essential travel and avoid supply chain disruptions."
