ฉันสามารถเข้าร่วมการดำเนินการเรียกร้องร่วมกันในออสเตรียเกี่ยวกับความล่าช้าในการคืนเงินค่าตั๋วเครื่องบินได้หรือไม่ และต้องมีหลักฐานอะไรบ้าง

Austria doesn’t have US-style class actions, but airline refund situations are in some cases handled via assignment models or bundled/group claims. Whether that’s an option depends very much on the specific facts (and there may currently be no such proceedings in your case).

Typically you’ll need your booking confirmation, cancellation notice, correspondence with the airline, and proof of payment. Claims are usually time-barred after 3 years from the flight date, and costs are often shared or success-based – if claims are brought together at all. Some passengers prefer individual enforcement, which often depends on the amount at stake.

It also matters whether this is about a late refund or no refund at all. Feel free to reach out with a few details, and we can quickly point you in the right direction.

Kind regards,
Simon Burger
