KLM1573 - booked flights via Qantas's rewards. Got a greeting from the CSM for the flight, and brought some snacks from J.
IB1756 - booked direct cash fare, got to choose extra legroom seats for free even as a basic ticket, allowed to use the Oro/Platino counter for bag drop-off. Also noticed that my friend, who was on the same PNR, was able to choose the extra-legroom seat for free. But did not get the extra benefits like express security. Personal greeting from CSM at the seat. Strange to get boarded before people with accessibility access (Group 0).
IB0413 - booked direct cash fare, like above, but my friend was not on this PNR, so he did not get to choose the seat. Got a similar greeting from CSM, but both Y staff came to greet after as well. The older gentleman who sat next to me looked very confused and mentioned that he had never seen this before.
BA770 - Very strict gate checking with bags being tagged for what can go above or below. Got both my bags waived and allowed to be stored above. When boarding was announced, I was allowed to board group 1 - one of the passengers tried to stop me, saying that it was for Business or status only (they tried to get on but got the denied message). Gave me a stink eye when my ticket worked.
