I'm sure they know how much you fly and your status with other Star. And I'm sure they're trying to persuade you to fly more often with them directly or otherwise.

Last October flew long haul LH and the purser instructed a flight attendant to serve only 3 pax on biz. She was speaking in German but pointed her fingers to me and 2 other pax. And throughout the flight, the attendant did only serve the 3 of us and no one else, even though the upper deck was quite full.

Different flight long haul LH this year, only 4 of us in mini cabin 747-8 and it was quite glaring on how I was treated better. Meal order first, level of attention, etc. Even better than being a SE on AC.

If given the opportunity, 110% sure I can achieve senator status yearly, and if I had to be in Europe on a regular basis, I'd take the purser's offer in a heartbeat.

Edit: I change my mind come to think of it. Biz is for sleeping and unfortunately LH has crappy seats and food. So I'd still stick with AC. But I do very much prefer their service and attention over AC. More genuine...
