Nah! I get called Dr. on some flights and on some not. And I do not have that bad experience and bad luck with you. (It seems that you are the the perfect proof of Murphies Law when it comes to LH!). That is just your Karma and not your academic title!
Some FA have great difficulties in pronouncing my name. Sometimes they just call me Doctor. BA just pronounce it as it is. QF is more on the Doctor side. LH ignores me, calls me with or without my title. When I call the AT-Hotline I just tell my name with the full title ;-)
