question about airlines

what airlines don't charge the extra charge for obese passengers? 

Thanks,

I've heard that the only one that doesn't is American Airlines.

thank you

we flew Delta to San Diego Feb 26th came back #/5  no extra charge Wifes BMI 54  We fit seats

thank you

A tip I got that I am following:

Choose a flight very early or very late in the day. Choose a window seat WAY in the back where no one likes to sit, try to choose one that already has an aisle (but no middle) seat reserved. Then, hope no one buys a ticket to sit between you!
