A television reporter who injured her ankle on holiday in Thailand has lambasted Jetstar for refusing to upgrade her to business class and making her pay for a pillow to elevate her leg.

WIN network reporter Jodi Lee posted a withering indictment of the airline on Facebook, after staff failed to accommodate her requests to ease the pain of her snapped Achilles tendon.

"@JetstarAustralia I am appalled at your blatant disregard for customer service," Ms Lee wrote on the airline's Facebook page, accompanied by a photo of her bandaged leg.

"[S]taff over the phone, at the check in counter and on board refused to upgrade my seat 'due to policy'," she wrote.
