I'm wondering if anyone can tell me if I should be entitled to compensation (I've yet to contact United).
I was flying MIA->EWR->GLA, the flight from MIA->EWR was 4 hours late so I was going to miss my flight from EWR. The alternatives offered by United would all have resulted in 12 hour plus delays. Instead I got my travel agent to book and pay me on a BA flight which arrived in GLA only an hour later than my original flight. The travel agent cancelled the United flight but as the cost of one-way was the same as return they didn't get any money back.

Can I claim compensation from United as the flight was to the EU?
