Icelandair has round-trip flights from Dallas (DFW) to Manchester (MAN) for $330-$407 in their “Light” fare-class. Flights scattered from September to December. Holiday blackouts apply.
Note: The $330-ish fares will have a 1-day stopover in Iceland on the return flight. If you want to check out Reykjavik this may be worthwhile. The $407-ish fares are more direct with normal connections. (We’ve broken the example dates into “Regular” and “Stopover dates”).
Note: You can upgrade to a “Standard” fare-class for +$100 more, which allows for a free checked-bag.
