On the BA824 17:20 departure LHR-DUB and we've got a mechanical issue (one poor couple are off the Las Vegas flight so they've had a rough day!). Delayed arrival is currently c 20:00 with my return flight being 20:45 on a separate booking and I've got checked luggage.

Any ideas? There's an Air Lingus at 21:10? Could I move on to that?!?!?
