i see people screaming and hollaring and i'm like you're not helping anything. >> do you ever get anythingscreaming works really well. >> i can't imagine you screaming at an airport? >> i don't, but i fear that people are taking advantage of me. >> go on to twitter and tweet politely at an airline, follow the problem and they will deal with your problem privately on direct message and then they can publicly say we're so glad we helped you. they get a pr win, they showed they helped you very quick. >> i hear about something called interlining. >> it is one of those industry terms that you should know. it is essentially make nice between the airlines. it involves a lot of things, but one of the things it can mean is if your flight is canceled another airline could accommodate you. you can end up on another carrier, but getting to your destination quicker. it won't apply in all circumstances, very politely ask, are there any interlining agreementing. >> they will be shocked that you even know the word. >> another reason not to yell at the ticket agent. keep that in mind. >> they're all human
