Greetings, I have a person who is significantly large and needs to travel with me. She's 5'5" and 360 pounds. I am generally aware of UA's policy from a quick check of their website (arm rest must fit down, 1 seatbelt extention). But if we could get her seated on the 1-seat side of an Embraer, would that change the equation at all? Maybe a bit more forgiving? Moreover, does it sound like she would fit? I plan to call UA soon with the same story but in the menatime, Anyone with experience , help would be appreciated.
