DDB & Tribal Worldwide Amsterdam has found yet another way to attach KLM’s extras to the hearts and minds of travellers.

In September, DDB & Tribal Worldwide Amsterdam developed “special technology” to make the KLM Lost & Found department at Amsterdam Airport Schiphol more useful to KLM travellers.

A search dog. That returned all that lost stuff people lose on planes.

In April, it invented an airport game, Flat or Not, to introduce its new World Business Class and its special full-flat bed seat. And gave one person a round the world trip for free.

Now KLM has launched Cover Greetings. The joint promotion film by Amsterdam Airport Schiphol and KLM on Facebook, YouTube and Twitter is the result of an idea by KLM’s agency, DDB & Tribal Amsterdam. Schipol’s agency, FHV BBDO, also worked on creative.

Loved ones left at home were able to send a personal message to their boyfriend, girlfriend or relative on the headrest on their KLM aircraft seat.

KLM spotted people saying goodbye to friends and families at the departure gate, then whisked the stay-at-homes away to a place where they could decorate a seat cover with their own message.

Schiphol and KLM staff then took the messages to the plane before boarding, and placed them on the seats of those who were travelling.

When KLM travellers found their seats on their planes, they also found that KLM had organised a heart-warming surprise.

KLM stated, “Through Cover Greetings, Schiphol and KLM have added a surprise to the time of departure to make it a special moment both for the passenger and their loved ones at home.”

The stunt took place on a single day, involving passengers from three different flights. The airline has since stated that it is considering turning Cover Greetings into a permanent service.
