Thomas Cook has issued an apology after failing to deliver tickets for the Olympics in time.
Some customers were advised two days before the start of the Games that they needed to pick up their tickets in London despite having paid a £5 delivery fee.
Cook said tickets could be collected on arrival, or prior to the event, at locations in central London, Heathrow and near the Olympic Park.
It is to look at individual cases where people were left out of pocket by the problems.
A spokeswoman said: “Thomas Cook can confirm that a small proportion of its London 2012 customers have experienced delays in receiving their Olympic tickets.
“As a result, the company has contacted them to ensure tickets are able to be collected in London.
“Our priority is to ensure our customers take their seat at the Games.
“Unfortunately, a very small proportion have experienced a delay and we’ve contacted them all to confirm collection of their tickets from a choice of locations in London.
“We’d like to reiterate our apology for this unavoidable delay and naturally we’re also refunding any delivery charges already paid.”
