The blind woman said that her guide dog was "squashed" in the footwell of her seat on two flights.
A coach at Barry Town United's pan-disability team flew from London to Canada with her guide dog.
She said she was worried about her dog's welfare on the flights. "Emily was at my feet the entire time, however for anyone travelling on a plane it's not enough space anyways and then put a dog at your feet it's even less space," she stated.
The third party that McBratney used to book her tickets did not contact the airline to ask for special arrangements.
Insider's request for comment was not immediately responded to by WestJet.
When McBratney took her harness off, she could see that Emily was not comfortable.
She was told by the airline to cancel her tickets with the third-party and book her tickets directly with the airline.
Five months ago, I booked my ticket and called the airline. McBratney asked for an extra leg room. She was told that they couldn't make the special arrangements at the time because she booked through a third party.
It was an eight-hour flight for anyone. It made it very difficult for both of us.
According to the Civil Aviation Authority of the United Kingdom, airlines are not obliged to seat passengers with guide dogs in the front row.
Guests with service dogs give at least 48 hours advance notice before their flight.
McBratney's options were limited because the third party had failed to do so.
