"passengers were obliged to go on standby. " what's the meaning of "on standby" in this sentence. Thank u in advance.:)
1st guess: they were forced to take unreserved seats (if available). they had no prior reservation and had to count on probable vacant lots.Originally Posted by gxiang
2nd guess: they had to be ready to help immediately if they were needed.
You should use the context. Both interpretations are probable.
