Has anyone ever needed to change the date of their assessment day. I've been asked to attend day 1 and the dates available are all around my simulator renewal with my current airline and those dates are not confirmed 100% yet. I've got a few reminder emails from BA asking me to pick a date and I'm wondering if I do and then cannot make it - are they happy to change? I've emailed them but no response yet, obviously I want to avoid messing them around while not missing out.
