Ryanair is going to sue the British government over its ‘traffic light’ system with travel advice. The Irish budget fighter is annoyed that the United Kingdom has few destinations on its list of countries without quarantine requirements.

Portugal was on the list for a while but was later removed from it due to an increase in infection figures.

According to the airline, which works with the Manchester Airports Group, there is a lack of transparency. They will file a case with the British High Court on Thursday to clarify exactly how decisions about travel advisories are made. Countries can fall into a red, orange or green category, depending on the risk of corona infections.

The aviation industry in Great Britain thought it would soon be able to transport many passengers and holidaymakers again. That’s because the British were very quick with their vaccination campaign.

Industry parties, therefore, regard the “opaque” way in which the authorities operate as a setback. They say this undermines consumer confidence to book summer vacations and would make it impossible for airports, airlines, and other travel companies to develop proper recovery plans.

The British government has not yet responded to the announcement of the legal action. Earlier this week, the government in London postponed lifting the lockdown in England by four weeks.

There, all restrictions on social contacts should have expired on June 21. But lately, there have been concerns about the rapid spread of the Delta variant of the virus, which originated in India. The delay should allow authorities to give millions of additional people a second vaccine dose before the restrictions are lifted.
