Omicron, the new variant of COVID-19 pandemic, is taking its toll on the aviation sector in the country.
Due to the global alert, measures by the United Kingdom, United States and Canada to curtail its spread have drastically affected international flight schedules, thereby creating discomfort for passengers.
Yesterday, many UK- bound passengers were stranded at the Nnamdi Azikwe International Airport (NAIA), Abuja and the Murtala Muhammed International Airport, Lagos.
Shortly after the flight cancellation, the British High Commission announced its decision to put on hold visitor visa applications from red list countries, including Nigeria.
The commission however, explained that from 4 am today, only British and Irish nationals and residents travelling from Nigeria would be allowed into the country.
The commission also said they must isolate in a government-managed quarantine hotel.
However, the Federal Government expressed displeasure at its red listing by the United Kingdom government.
Canada also introduced new guidelines, including the rejection of results of molecular COVID-19 tests done in Nigeria and nine other African countries.
The U.S. said air passengers boarding a flight from a foreign country to any of its airports must get a COVID-19 viral test, regardless of vaccination status or citizenship, no more than one day before travel.
