Japan Airlines has suspended a sales campaign after its website for reserving and purchasing air tickets became almost inaccessible.
JAL says the problem started late at night on Wednesday when access to its website surged ahead of the launch of the campaign on Thursday.
It was impossible for customers to book or purchase tickets for domestic and international flights on and after April 12 through the website, in addition to the campaign tickets.
The carrier says it decided to suspend the campaign, domestic air ticket time sales "JAL Smile Campaign," to resolve the problem.
The campaign offers all domestic flight tickets for April and May at a discount price of 6,600 yen, or about 48 dollars.
JAL says the campaign for June flights that are scheduled to go on sale on Sunday will also be cancelled.
It says that it has not decided when to restart the campaign, and offers its sincere apologies for any inconvenience the problem may have caused.
