British Airways directors will be touring terminals this weekend

More than 100 flights have been cancelled in six days of travel disruption due to staff shortages and technical problems.

Six flights were axed on Saturday, but BA says the worst is over.

A spokesman said directors would help out and greet passengers but not fill in for regular staff.

Mr Eddington has previously admitted the company made mistakes.

"Clearly we did get it wrong because we didn't have enough people in the terminal on Monday," he said on Wednesday.

We let ourselves down ... our customers and our own people BA chief executive Rod Eddington What caused travel chaos?

"We know we're short-handed in the terminals. We've got 200-plus people in the training system to address that, but yes, we let ourselves down on Monday night, our customers and our own people."

A BA spokesman said on Saturday that Mr Eddington and the other directors would be touring the three terminals over the Bank Holiday weekend, talking to staff and passengers, but would not actually be working because they were not trained in procedures such as check-in.

The six flights cancelled on Saturday were out of a total 540, and the spokesman said things were running "pretty normally".

The airline has warned services may be "merged" in coming days to cope with the problems, but said any changes would be made well before departure times.

Thousands of passengers were left stranded after cancellations

The disruptions began on Monday when BA ditched 50 flights from Heathrow due to technical problems with some transatlantic aircraft and staff shortages.

The knock-on effect of having planes and crews in the wrong place resulted in a further 31 cancellations at the airport on Tuesday.

Another seven were cut on Wednesday, prompting BA's director of operations Mike Street to apologise to passengers.

The airline thought it had avoided any holiday weekend problems when it struck a pay deal with check-in staff and baggage handlers, averting a planned strike.
