Starting today, airlines may “interview” you before you board a flight to the US

Be prepared to be interviewed by your airline just before you hop on the flight to the US. Starting Thursday, 26 October, 2017, new security protocol laid down by the US requires airlines to put passengers through additional screening. This applies to all passengers flying into the country on any airline from anywhere in the world.
It isn’t fully clear yet how the screening will take place. Some airlines may hand out a questionnaire, while others may throw in a round of interviews before boarding. What is also not clear is what will this questioning entail. Cathay Pacific said its passengers will be subject to a short security interview at the check-in counters at Hong Kong airport. Those without check-in baggage “will also be subject to a short security interview” at the departure gate.
