Avoid flying back to the US through Frankfurt if you are not StarAlliance (Lufthansa, Unites, etc). AA is flying out of terminal D...a terrible terminal.
I travel to Europe often and this time flying back to the US on American Air through Frankfurt. I'm Concierge Key on American. This review is not on AA but on the airport layout, security and lounge, prior to boarding. This is terrible...Why would a lounge place prior to security check? It's never the case at other airport, including Terminal 1 at Frankfurt which serves Lufthansa and Star Alliances.
Then the security line is terribly long, because they habe to process other US airlines. Once you passed the security check and to the waiting area, there's hardly any thing to buy if you're hungry or thirsty. read more
