Passengers who have booked well in advance are advised to reconfirm their flight times between 24 and 72 hours prior to scheduled departure 难道说这意味着,出发前还要再确认一下吗?如果是,如何确认呢?没看到有电话号码呀。
You then noticed that the four shortest times all had a paper clip attached . you reasoned that paper clips probably did affect these flight times . you were right again 您会发现四次最短的飞行都有一个回形针,您推论出回形针影响了飞行的时间。你的推论也正确。
