I need to book a flight to Barbados in March and I would like it to be VA for the miles. I only need the flight one way as we shall be cruising home. Looking on-line, the cost of a one way UC seat is £2,943, whereas the cost of a round trip seat with the outbound seat in UC and the return flight in Economy is is £1,233. Is there anything to stop me booking the roundtrip and just no showing for the return? Unethical technically but £1,700 is a lot more to pay to be ethical. What do you think....will they chase us up for the extra fare if we don't show up for the return flight?
