I am here to correct a mistake many are making. It is only the LHR/LGW reports on strike days that require BALPA members to not work. When down-route you are not required to take IA. So flights arriving on strike days are NOT performed by non-strikers. Most pilots down-route have had trips extended by up to 5 days. Many of these have pledged the extra duty pay this has triggered to the benevolent fund.
