The planned strike by British Airways (BA) cabin crew has received growing support from a number of unions around the world. Unions representing airport workers in France, Germany and the US have pledged their backing for the walk-out.

US union leader, James Hoffa, said that BA operations could be interrupted if action will also be done at US airports. However, it is not clear what form of legal action the US group could take.

BA earlier informed that it will be able to service 65 per cent of its passengers during the planned strike by trade union Unite. The three-day walk-out is due to begin starting this Saturday.

Meanwhile, a three-day strike by staff of Air France has also been scheduled for 28 March to coincide with Unite’s action. A French union spokesman told the Daily Telegraph that the group would do anything it could to support BA’s strikers.

BA claimed that at least 1,000 staff have offered to temporarily fill-in for those who will be striking. The UK national airline informed as well that 60 other carriers are now offering to help fly its passengers during the strike. But Unite accused the airline company of bluff, saying that only 350 volunteers are ready to stand in for the strikers.
