I got to tell you, that spreadsheet is pure genius. Any way of finding out when prices change? For example, will this spreadsheet be updated when Cairo fares change? I don´t know who spent the time to creat this but I love it!
I´ve created a similar spreadsheet that calculates miles between airports, but unfortunately it only contains data that I´ve input myself, that I´ve looked up, I´d love to be able to hook it up to some online database that would download all that info, but unfortunately don´t know where I could get all that info.
