A few days before they were supposed to travel to Israel for two weeks, a close friend of mine asked for a ride to the airport. I called, using a blocked phone number and said, “Hello, Mr. Schwartz this Sarah from El AL, I’m sorry to inform you that you will not be able to bring any luggage on the flight you have scheduled for tomorrow.” Because it was a close friend, I knew most of the basic information (name,address, number of travellers, etc.) plus what time the flight was, so I was able to make my call seem very legitimate. I went on saying that I would be able to book him on a flight, with two connections in Paris and in Frankfurt, with an added cost of $400 and in this way he would be able to take luggage. After a few minutes of letting it play out, I hung up and called him back, as myself, just to confirm the time of the flight…
Everyone got a good laugh, no harm done.
