Lynx Air says Sabre Corp. has “refused to assist” with passenger reimbursement for the now-defunct ultra-low-cost carrier, which ceased operations and filed for creditor protection in late February.

Lynx claimed in court filings that the firm hired to handle bookings, Texas-based Sabre Corp., has hampered passenger reimbursements.

The ultra-low-cost carrier said it had planned to carry out refunds directly, “without the need for customers to contact their credit card providers to submit chargebacks.”

“Unfortunately, Sabre Corp…. has refused to assist with customer refunds,” according to an affidavit from Lynx’s interim chief financial officer and filed with the Alberta Court of King’s Bench.

That leaves the airline no choice but to work with its credit card processor to deal with chargebacks for would-be travelers whose flights were cancelled, the filings state.

While customers wait to have their purchases refunded, the company’s investors may also have a harder time recouping their own cash from Lynx.

“The chargeback process is expensive, and this will therefore result in significant chargeback fees to the applicants” – Lynx – “to the detriment of their stakeholders,” the carrier stated.

Sabre Corp., a travel technology firm with clients in more than 160 countries, declined to respond to questions.

“As a matter of policy, we don’t comment on our customer agreements nor do we comment on legal proceedings,” said spokeswoman Heidi Castle.

The deadline for customers to submit chargeback requests is Sept. 1, 2025, court documents say.

The shutdown of Calgary-based Lynx comes as the budget airlines that have cropped up in recent years face ongoing financial pressures — if they’ve survived at all. The tough market stems partly from industry consolidation and fallout from the travel sector implosion during the COVID-19 pandemic.
