So Im in the EK lounge here in Paris having just checked in Im recenty down to silver after many years as gold having not flown west of India much over the past 18 months, (except London which has many convenient direct options from Delhi).

I have a business class ticket and checked in at that counter. Before my bag left, I noticed that the priority tag (the Blue one) had not been inserted. So I requested the agent to do it. He looked uncomfortable and then did it. I asked him whether anything was the matter and he said they only put these tags on for Golds and Plats -- even if flying in Business, but did it for me as a favour! I thanked him for the favour and decided to seek clarity on FT

Now I flew to New York and back last week and to Abidjan a month ago from Delhi in Business/first and my bag was always tagged priority with the appropriate Blue or Red tag at all three stations So this I know is not a universal rule.
Is this something specific to PAris or a brand new rule that EK has instituted? Any ideas?
