Huh, I tried a SEA-LON ticket, best price $1363 on Kayak.<p>TripDelta found me a $655 flight, except out of Portland (which is like a 3 hour drive away), and a $750 flight that looks like<p>SEA-EWR &#x2F; JFK-LHR<p>which is a hell of a connection. I couldn&#x27;t deal with the inconvenience, but even so I&#x27;m kind of impressed.
