Omio marked my trip as completed even though I never traveled, how is this corrected?

If Omio marked your trip as completed even though you didn’t travel, that’s usually a status issue on their end or with the transport provider’s reporting — not an actual travel record — so the first thing is to review the booking in “Your Bookings” and confirm the ticket details and travel dates in your account or confirmation email.

Next, contact Omio Customer Support via the Help Center with your booking number and evidence (screenshots/emails) and ask them to correct the status and process a refund if you didn’t travel; if you had Omio Flex or a refundable fare, they should refund up to 90 % of the ticket before departure.

If not, file a complaint on Xolvie to seek a resolution.
