British Airways next round of strike action may coincide with the Royal Wedding on April 29, Union members have warned.

Such an action would cause disruption at a time when tourists are expected to flood the capital to catch a glimpse of Prince William getting hitched to his long-term, commoner girlfriend Kate Middleton.

Royal Wedding plans revealed

One union source told The Sun: “We don’t want to do it, but if it has to be done to solve this dispute, so be it.”

Unite, the union which represents BA cabin crew could choose Easter or the Royal Wedding as a time to strike to maximise the damage.

11,000 BA cabin crew members are due to vote on strike action in two weeks over the removal of travel concessions for workers.

They are expected to vote in favour of instigating new strikes in their ongoing, bitter dispute with the airline.

London Underground drivers are also threatening to strike on April 29 over demands for more Bank Holiday pay.

Tube strike looms for Royal Wedding

A Downing Street spokesman said the tube strike on Royal Wedding day “would be seen as a cynical attempt to undermine a day of national celebrations”.
