Yep, definitely 75D/H equipment and they are selling it as a domestic F flight -- fare code QA7IA0FQ. Second letter from last identifies it as domestic F. D1 flights will use a fare code with a 'D' in the second to last letter. Flights on D1 equipment on this route will be actual D1 flights starting Apr 1, but non-D1 equipment will still be considered regular old domestic F (no lounge access). IT systems are apparently confused by the distinction.
