This back and forth...and then back and forth discussion about staff travel can be interesting but there are a few absolutes in play.
Can BA remove Staff Travel from striking cabin crew members? Yes. The proof is in the fact that they have done so.
Was BASSA correct in telling their members that they would have Staff Travel back in "five minutes" if it was removed. No. My watch says they missed that call.
Will the removal of Staff Travel stand an examination of a Court hearing? No one knows because the only party that has an interest in such a hearing has failed and/or refused to bring an action forth on behalf of their members.
The fact that neither BASSA or Unite have done so should be of concern to those Cabin Crew who have lost staff travel due to their reliance upon their Unions' representations.
Any member deciding to participate in future IA should do so with the sure knowledge that BA can and will withdraw this perk and it will stay withdrawn for more than the "five minutes" BASSA represented.
