Kerry Deane, 32, was travelling back from Tunisia when air staff demanded she be examined to determine if she was fit to travel.
The 35-year-old already had documentation from her GP saying she was allowed to fly, but she was still forced to the front of the plane, where staff took her blood pressure, felt her bump and carried out the internal exam.
She was then told, along with her partner Gary and their three children, that they would need to leave the plane.
The young family then had to hang around in the airport for hours until they were placed on a flight to Newcastle - 150 miles away from their home in Lanarkshire.
Kerry is now seeking legal advice on the matter, saying the way she was treated was ‘an absolute disgrace.’
‘They didn’t carry out the examination in any sort of sterile way, and I can’t believe we were thrown off the plane as it was obvious I was not in labour.’
A Thomson spokesperon said: ‘On this occasion the flight was not operated by us but by a third party airline. As every airline has its own policy regarding flying during pregnancy we advised Ms Deane to speak directly to this airline prior to travel to avoid any potential issues.
‘As we understand Ms Deane has instructed a solicitor, it would be inappropriate for us to comment further.’
