Trend suggest an AGM in the week 17 - 21 was on the cards.
So for a start TRA delayed AGM by a week.
Given the 6 day variability (14 - 20th) you'd think you wouldn't go booking a non refundable trip 6 days either side of usual parameters.
And if he had booked a non-refundable holiday a year ago, thats plenty of time to organise an AGM around it.
I dont think there is any conspiracy theory - just poor form.
