The 33rd festival takes place at venues across the city between November 6 and 21.
-> Leeds International Film Festival 2019 needs volunteers - here's how to applySome customers are disappointed that the flat fee offered in previous years - allowing two weeks of access for £100 - has been replaced by a LIFF Explorer, for which fans can pay £50 for full access but are required to pay £3 ticket per film after that fee.
A spokesman for Leeds Film City, which organises the festival, said: "Regarding the pass process, we are going to be addressing that at the start of next week."
He could not say whether that would be in the form of a statement or a change to the pass structure.
Asked about a rumour that ticketing has been affected by a lack of European Union funds, he added: "The change in the structure isn't related to Creative Europe."
In a post on twitter, LIFF organisers said "we realise that previous LIFF goers have been surprised by the move away from a flat fee pass," adding: "We apologise to any attendees who had planned ahead based on our previous pass structure, and hope that you will still be able to enjoy many festival events."
Creative Europe is a €1.46 billion European Union programme for the cultural and creative sectors for the years 2014 to 2020.
It supplied some £60,000 for LIFF in 2017, 12.09 per cent of its budget.
As Brexit looms, future EU sources of funding for the UK remain in doubt.
