I am always aware of the type of plane I'm scheduled to fly. I fly 3-4 times a year, and can tell you for a fact the type of planes I'm scheduled to fly on the remainder of the year. I'm one of those 'aware' travelers who pays attention to that. My next flight is an Embraer on United from MSP tp EWR, and from there, on a United 767-300 to TXL. Without looking, I can also tell you our seat assignments (realizing those can change). I'm just the type of traveler to pay attention to that. So, when I say I will not fly a Max 8, I can tell you affirmatively that I would avoid flights where that was the scheduled aircraft.
