I have been searching for flight tickets from Madrid to Medellín (Colombia) on google flights and I found really good ones. Then I had to click the button to book tickets from American Airlines, the new window popped out and the website really looked like the American Airalines' (big logo and everything). However I noticed that the name of the www was https://bookaa.amadeus.com . So I was wondering, is this legit or not??? Have you ever booked tickets from there?
