SunExpress Online Check-In Error WS_750 Not Fixed for Days
I have been trying to complete online check‑in for my SunExpress flight on 25.07.2026 since 22.07.2026, but your system has been giving the same error for days. Each time I attempt the online check‑in, I receive the message “We are updating our systems. Please retry shortly or complete the form to ensure free-of-charge airport check-in. (Error code: WS_750)” and the process cannot be completed. For an airline, it is not acceptable that such a basic and important function like online check‑in remains unusable for more than 24 hours without being resolved. This creates uncertainty for passengers and undermines confidence in your digital services. I request that you urgently fix your website and online check‑in system so that customers can reliably use the service as promised, and I ask you to review your technical processes to prevent such long-lasting issues in the future.
I have just tried to call the hotline.... This is absolutely inacceptable. You can go through menus just to listen to clear the browser cache and to hear goodbye and a sunny day... No chance to speak to a person... So they will charge an additional fee at the airport check-in.. Unprofessional...
