Hints：
in-flight
Few people expect luxury while flying, but these days, even the basics seem to be in the bad shape. It's not uncommon to find your tray table broken, the in-flight entertainment system not working and your seat cushion worn.
很少有人会指望在飞行途中能有奢华的享受，然而近些天来，恐怕连基本的服务都难以保障了。发现你的托盘桌坏了，飞行途中的娱乐系统也不给力而且你的坐垫是破的也不足为奇。
