Have an idea for improving the air travel experience?

Seven “Quality Hunters” recruited by Finnair and Helsinki Airport have spent the last five weeks traveling around in search of ideas to improve the air travel experience.

Now, during the final week of Finnair’s Quality Hunter campaign, Finnair and Helsinki Airport (home to a spa with saunas and a swimming pool)are inviting the public to send in more ideas.

There are prizes to be won for the most innovative submissions which, so far, include everything from in-flight karaoke to virtual chess games, ‘hush-hush’ seats, reserveable overhead bins and, something I’ve been advocating for years, airport speed dating.

The deadline for turning in ideas is November 29th, 2011. After that, Helsinki Airport and Finnair will choose some finalists and invite the public to vote on the best ideas.

See all the ideas – and add your own – here.
