Preface: I'm a loyal Delta customer.
This morning I waited for a flight inside a Delta lounge at Salt Lake City's airport. They offer free WIFI and once you agree to the terms and conditions they redirect you to the Delta Sky Club portal, a mostly useless page featuring not much more than weather from a city that's neither my current location or destination, ads probably injected by the vendor that maintains this portal for Delta, and a few airline and news headlines that are completely irrelevant to my travel. We're all familiar with these pages -- you usually run into them anytime you use complimentary internet at hotels and airports, and they're total junk.
What a missed opportunity to improve their customers' experience.
So, I decided to join the rank of designers who offer unsolicited advice to airlines (Most notably Dustin Curtis' letter to American Airlines) and gave myself an hour's time-limit to rethink this Delta page, with their current look and feel as a constant, in order to demonstrate a fairly simple page that is dramatically more valuable.
You might ask how an airline is supposed to know who is who so that they can show each passenger's private data. My idea is to require your frequent flyer mile number in order to access free WIFI (almost everyone in a lounge has a number) and perhaps even use my Delta.com cookie to autofill it. If a passenger doesn't have a number, give them an opt-out and take them to the old portal for now.
If I had another hour, I'd clean up the grid, add more details and history about the airplane you'll be riding (dataporn), emphasize actions (like "Change your seat") in a more distinct way, and add a row of icons to summarize the perks of your flight (WIFI, Food, TV, Business Class, etc).
Update: Would like to show weather advisories, design state for delayed flight.
