A woman with multiple sclerosis has claimed a US airline was inadequately equipped to deal with her needs on an international light, claiming she was tied to a wheelchair.

Maria Saliagas was diagnosed with MS five years ago however has continued to make her annual trips with her husband to Europe.

On April 1 she was scheduled to fly from Atlanta to Amsterdam and ahead of that trip her son made the necessary arrangements with Delta officials to ensure a proper wheelchair would be waiting for her on arrival in Amsterdam.

However, the wheelchair with special straps to help her sit up straight wasn’t there, Nathan Saliagas has claimed.

“They took a dirty blanket and tied her forcefully with it, and she has bruise marks on this part of her arm, which is where it was tied,” he told WSB-TV, pointing to his bicep.

“I want them to show initiative that they’re willing to change their disability services.”

After complaining to airline staffers Saliagas was offered 20,000 free SkyMiles however, her son says that won’t cut it and instead she wants assurances that in the future they’ll better accommodate disabled passengers.

Delta Air Lines has apologised.

“We are disappointed that our customers didn’t have a satisfying travel experience and will ensure that their return flight exceeds expectations,” the airline said in a statement to The Post.

“While Delta always looks for ways to improve the overall customer experience, our findings do not align with details shared by the customer’s family.”

However, the airline is disputing Saliagas’ son’s version of events.

They claim an airport-contracted wheelchair vendor did meet Saliagas at the gate in Amsterdam.

They say an aisle chair, designed for in-flight use, was used to help Saliagas off the plane and once off the aircraft several wheelchair options were offered to her and she picked one.

However, after being seated in the wheelchair Saliagas said she was “slipping”, prompting the wheelchair assistant to suggest using blankets to secure her to the chair.

This was allegedly agreed to by Saliagas and the blankets were new, not dirty as her son claimed.

In an earlier statement to WSB-TV, Delta said it regretted the “perception our service” left on Saliagas.

“We have reached out to them, not only to resolve their concerns, but also to ensure that their return flight exceeds expectations,” Delta officials told the station.

Saliagas’ son Nathan further criticised the airline in a Facebook post.

“Delta Airlines on April 1st, from Atlanta to Amsterdam, decided to physically and emotionally abuse my mother, a woman who suffers from Multiple Sclerosis,” he wrote.
