The Treasury has told ITV News the Chancellor had a diary change and he and his aide got a different train. They say that their existing seat reservations did not apply.
The train was crowded so they decided to upgrade from standard class to first class and they always intended to pay the difference.
It says the Chancellor is not aware of any row with a ticket officer.
The country's national newspapers have offered their reactions to the George Osborne ticket row, broken exclusively by Granada Reports.
Cheshire MP George Osborne has argued with ticket collectors after he refused to sit in standard class on a train to London.
