Cabin crew members for British Airways are holding a 48-hour walkout in protest of the 'poverty pay' they are receiving. The walkouts have resulted in 44 flight cancelations since yesterday. The cabin crew members are being represented by Unite and have been employees of British Airways since 2010. The protestors are considered 'mixed fleet' members and are paid substantially less than regular crew members.
