Well done Brandon! Great pictures and report...
It is so frustrating when you've carefully selected flights for a reason ie aircraft type, and they go and change it. It is hilarious about what happened to all four of your flights - what are the odds.
I actually missed out on going to the airshow in 2011 because "Tiger Airways" rescheduled the morning flight to be a lunch time flight, only a couple of weeks before the airshow, so I couldn't go as remaining airfares on other airlines were very expensive.
I was apparently getting a refund from Tiger for this, and I never received it despite following it up many times...
Keep up the good work...
