Well I got a text in the night to say "flight delayed five hours" so I've been keeping an eye on departures from Cuba and his flight has now left Cuba destined for Gatwick Airport. On the last check he was roughly half way - some where over the ocean. Still another 4 hours 45 minutes to go. He should get into Gatwick around 8.00 ish this evening.
Unfortunately I'm out this evening but will update later.
