Airlines UK said continuing the current testing measures, which includes a pre-departure test prior to arrival in the UK and a subsequent PCR test on or before Day 2 of return, would be "financially disastrous" for the industry.
Manchester Airports Group (MAG) claimed pre-departure testing has had "little or no impact" on the spread of the Omicron variant.
Tim Hawkins, chief of staff at MAG, told the BBC’s Today programme that research commissioned by the group showed there was a "basis for taking out all tests" related to international travel, due to the high number of Covid cases in the UK.
