Do Cathay Pacific offer hand baggage only tickets on long haul flights?

I am asking as earlier this evening I tried to book a flight from Manchester to Hong Kong with a firm called Lycafly. The price had come up in the Momondo screenscraper at £362 but perhaps fortunately the transaction was red flagged by my credit card company so I gave Lycafly a call intending to use an alternative card.

The agent on the phone was confirming the flight details but then casually dropped into the conversation that I was booking a hand baggage only ticket !!!! He offered a more expensive flight if I wanted hold luggage but I declined because it all sounded a bit fishy. There was nothing on their website stating hand baggage only although there was no mention of baggage whatsoever.
