He told LBC: “For passengers requiring wheelchair support we have more demand than we had before the pandemic.
“Why is that happening? Some of this is because people are using the wheelchair support to try to get fast-track through the airport.
“That is absolutely the wrong thing to be doing.
“We need to protect that for the people who most need help.”
“If you go on TikTok you’ll see that that is one of the travel hacks that people are recommending.

A video showing a passenger skipping queues at Ibiza Airport, Spain, by feigning injury to get a wheelchair has been viewed 2.5 million times on TikTok.

Mr Holland-Kaye added that about half of arriving passengers who request assistance only do so once they are on the plane.
He urged people who “really need the service” to let Heathrow know “well in advance so we can make sure there are enough people there to meet your needs”.
Many travellers using the airport this summer have faced long queues, with the situation blamed on staff shortages.
A cap on daily departing passenger numbers was introduced earlier this month to ease the pressure.
