Brief thread from a non EU person whose recent United Airlines flight from Portugal to the US was delayed for over three hours. When flying inside of or out of the EU you may have a right to compensation under "EU 261" on top of your actual expenses. I was only faintly aware from watching a travel video some years ago of such a thing or maybe from older posts on this forum. ( Some of you veteran travelers are saying no kidding Sherlock!.) Anyway, after returning home to US from our delay, I did not receive any compensation notification on this EU provision from United so did my own research. I wont repeat it all here as there is plenty on the web outlining the circumstances of eligibility, compensation amounts if due and steps for seeking from your carrier.
My main purpose in this post is to plant the awareness seed for other rookie EU travelers. In a perfect world your carrier would notify you automatically but apparently we aren't there yet. Also, when I did receive a response form United to my filing(quick by the way), their Customer Care agent offered Travel Credits or United Points as an alternative to the Euro$ as spec'd in the EU provision. Both this options were less value than taking the $. Happy Travels!
