Just returned from New Delhi, if you remember KLM lost my luggage on the way over--and they delivered it the same day I was to depart, so I petitioned them for a business Class upgrade, on the Delhi to Amsterdam flight it was full--but the Amsterdam-Houston the Purser was very accommodating and compassionate and bumped me up to the Galley of the 747-Homer rode in style. I kept thinking was a difference a few feet make in service, style, COMFORT (I could stretch out my legs). The food: Excellent+++, and all served in glass or ceramic dishes.
So KLM redeemed themselves and made a very good impression on me.
I caught them doing something right.
The next time you have lost baggage give remember to ask for an upgrade----you'll just say keep my luggage from now on.
