If print books are no longer selling comprehensiveness, then what is it they are selling?

如果印刷书籍的卖点不再是信息全面，那么它们的卖点是什么呢？

Kuwait Airways is no longer selling tickets for flights between New York and London after the US Department of Transport threatened legal action against theair line's policy of not allowing Israelis to board its planes.

科威特航空公司出台政策不允许以色列人登上其航班，美国交通部威胁对其采取司法行动，科威特航空不再出售纽约和伦敦之间的机票。
