Hi Guys. Based on the excellent ex-INV prices to LAS, I'm considering a B2B to position and then start the LAS ticket. I'm risk averse and in the past have always flown the night before, but encouraged by the reviews I'm thinking of a B2B. Is the plane we return on from INV going to be the plane we arrive on, so if we are delayed, the return will also be delayed, or is there a risk if our LHR flight is late? We would be HBO, so this seems the only risk, (early October so hopefully no weather issues) then we could return and sleep at LHR and start the transatlantic the next day. Is this the best way or would you suggest arriving the night before? Any advice would be appreciated, thank you.
