I don't mean to pick on United Airlines,so in the interest of fairness,let me also pick on Delta Airlines.Its breezeway---a dedicated entrance at each gate that allows elite passengers priority boarding anytime---is equally flawed,to hear passengers talk about it."It's a joke.And the announcements they make during boarding are even more ridiculous.This is just my opinion."

这一题的答案是NG（原文没给出来的）：The majority of American airline companies treat passengers differently based on their social status.

疑问：原文中的两个Airlines 不就是The majority of American airline companies 吗？下文的意思有也符合后半句的意思吗？
请指教！！！

既然只提到两家航空公司，能说明是大多数吗？

从意义上看，作者想要表达的意思可能是（证据不充分）：The majority of American airline companies treat passengers differently based on their social status.
