Johnny went to Yellowstone National Park this week for the first time. This week's app is FlightRadar24. This will show you all of the planes in the sky, and where they're going. Very fun for aviation geeks.
This week's website is CrankyConcierge.com. They will help you change your flight, monitor your flight, and even plan it. All for a fee, but it's what a good travel agent does. Another app is GoodRX. If you get sick while traveling, it'll tell you the nearest pharmacy and what the prices are for your prescriptions. There's also TravelSmart which gives you a drug dictionary with international translations.
