KLM moves passengers to tears with surprise greetings from loved ones

Airport farewells can often turn into a show of waterworks, as people separate from their loved ones. A heartwarming new video from KLM Royal Dutch Airlines captures several of those weepy sendoffs, and then keeps the tears flowing by surprising passengers with on-board greetings from the friends and family they just left behind.

In the KLM "Cover Greetings" campaign, folks are recorded saying tearful goodbyes to each other at Amsterdam Airport Schiphol in the Netherlands. KLM employees then usher those left at the airport into an area where they use colorful markers to write personal messages that will be attached to the seat headrests of their loved ones.

Once on board, the passengers react emotionally as they are surprised with the messages.

“My sister wrote this," says one woman in the video. "So I’ll miss her. I’m not going to cry anymore.”

While the video is sure to tug at the heartstrings, keep in mind that KLM is the same airline who recently warmed our hearts with the story of a sweet airport dog whose job was to reunite people with items they'd lost — and which turned out to be an advertising stunt.

KLM did not respond to a request Monday for comment on the campaign.
