what I assume is highly attractive to the airlines and consequently their customers You have to be certain that it is highly attractive...enough for them to pay you money for it. You're also going to face a huge hurdle with bureaucracy and proprietary technology (if it's an app). I worked for a hotel marketing company a few years back, and we had a proprietary booking engine that connected in house reservation systems with web-based ones. There was a team that went around just building code on top of each hotel chain's proprietary software that would tie into our system. I had a similar idea for a comparison shopping app back in 1999 where I would compare prices between different brick-and-mortar stores and allow people to shop online for a list of items, and show them on a map the fewest stores with all of the items at the cheapest price, or the cheapest price, regardless of the number of stores, or the shortest drive with the lowest price. That never got off the ground because there is no easy way to get all of the stores to give you an up to date XML feed of their current inventory and prices. Not in 1999 anyway...maybe it could be done now, but I'm not so sure. My idea was that I would start with a website in 1999, and maybe in 10 years we would have mobile technology that could take advantage of the backend data. I was right about the technology part. I'm not sure what your idea involves, but I would try contacting a few airlines to see if it really does solve a problem, and if so, how many more does it create?
