The Senate on Wednesday said there were indeed disparities between the fees charged Nigerians and other Africans by the British airlines operating in Nigeria.
The Senate faulted the position of British Airways, one of the British carriers in Nigeria, that the disparity only existed in higher class tickets and not for the economy.
Virgin Atlantic is the second British airline operating in Nigeria.
The Senate said while a first class return fare is $10,816 for a Lagos-London flight and the Abuja-London return flight costs $10,144, the Accra-London route costs just $4,798.
The Senate also said a return economy ticket on the Abuja-London route is $1200, which does not apply on other routes that are much longer for the British airlines.
The Senate has thus ordered its Committee on Aviation to probe the matter.
The Minister for Aviation, Stella Oduah, first raised the alarm based on the reports of a government investigation.
Oduah gave both British Airways and Virgin Atlantic 30 days to rectify the disparities or face sanctions.
But BA, in a statement by its media consultant, Quadrant, denied the allegation.
It said its fares were fair and equitable.
