Just finished reading this TR and your others, fantastic read. Some pointers
1. Great sense of humour, don't know if it was intentional but had a few chuckles to myself.
2. Thanks for pointing out that images can be embedded into posts, no longer will I have to open 20+ images in new tabs!
3. Thanks for putting the airline name after the code, there's nothing worse than assuming everyone here knows what every code stands for
