Rangers say they have been left in an "almost impossible situation" after the latest U-turn by the French government that means travelling fans can attend Thursday's Europa League game in Lyon.
It comes less than 24 hours after the Ibrox club, who had been allocated 2,220 tickets, were told away fans were not permitted at the final group match due to stretched police resources.
Rangers say the situation "continues to cause uncertainty and frustration with many supporters having cancelled their flights and/or accommodation".
The club, having cancelled their corporate flight on Monday which cannot be rearranged, are working with travel partners to discover if they intend to provide travel to the game.
"We apologise for the inconvenience caused to our support who will share our frustration at this situation," Rangers' statement added.
There is nothing riding on the tie with Lyon already through as group winners, while Rangers have second place sewn up.
On Monday, Rangers described the decision to ban travelling fans as "bemusing and extremely frustrating".
Lyon will be staging its traditional Festival of Lights and Rangers were notified via the French minister of the interior that this would "test the policing resource and city infrastructure".
The disappointed Scottish champions "made representations" to Uefa, the host club and "the French authorities", with the decision now overturned at short notice.
Rangers will face one of eight teams dropping out of the Champions League over two legs in February for a place in the last 16.
