British Airways chief executive Willie Walsh initiated a severe attack against union bosses as the row over cost-cutting became intense after the announcement of seven days of strikes by cabin crew.

Unite revealed that thousands of its members will remain on strike for three days from March 20 and for four days from March 27 after the all the talks aimed at reconciling a long-running brawl over jobs, pay and working conditions failed.

He is revealed to accuse the union of being entangled in a time warp and said it was blind to the difficulties the airline encounters in the worst recession witnessed for 80 years.

Unite has announced its plans to ballot its 12,000 cabin crew members on an offer from BA.

BA is revealed to temporarily withdraw the selling tickets on flight scheduled for the strike days, adding that until it revised its flying schedule next week.

All the passengers who have booked for the airlines between March 19 and 31 will now have to opt for either rebooking or cancelling and obtaining a refund.
