Surveys seem to be the latest obsession of companies- almost every checkout receipt from a big box store or chain restaurant has a survey link, and DL, like so many companies, does constant surveying. However, most surveys are exceedingly superficial and badly designed. I just got an e-mail request from DL for yet another survey, this one for a recent TATL flight. Four questions, two about the speed and courtesy of immigration, one about baggage claim, one about navigating the airport. I have global entry and had no checked luggage, so the first three questions were irrelevant and my answers would skew the survey unfairly. There was on choice to put n/a as an answer. What's with this survey madness fad among corporations nowadays? Do they actually think they are gaining any insight from this stuff?
