Betty Girl you seem woefully misinformed. Where did the unions ever accept or request mixed flying? The proposal for mixed flying comes only from BA and has never been accepted by the unions for existing crew members. The other examples you cite about what shorthaul pursers would and wouldn't accept are frankly immaterial too as they have not featured in the discussions. If you want to make a contribution to this highly charged debate it would be better if you came armed with the correct facts and not to post your own views as though they are part of negotiations, as these threads are already soaked in half truths and falsehoods.
