Recently I learned about two websites which will be useful in traveling.
www.fly.faa.gov shows a map of the US with flight delay information. It is not specific to your airline or flight number. But it does show cities where flight delays are occurring. This could be useful if you have connecting flights or are wondering where weather is hindering flights.
www.go-today.com is a Seattle based company that offers deals on European vacations, packages, etc. This is definitely worth checking out the next time you are looking at a trip to Europe. Friends have used this site and love their customer service.
