American Airlines has New York JFK to London Heathrow at $468 round trip for nonstop flights in late October.

Icelandair has several dates from late October into early December at $419 round trip for New York JFK/Newark EWR to London Gatwick, which is probably the catalyst for these low American Airlines fares. Icelandair allows a stopover in Reykjavik that usually raises the ticket price by only around $15. Also, no charge for seat assignment, carry-on or two checked bags with Icelandair.
