Heathrow's better than JFK

So for those of you following along at home, here's the deal: Iberia airlines has planes that occasionally develop holes within the fuselage. Luckily for those of us flying with this Spanish airline that means they spend some time fixing it. Unfortunately, this means flights are cancelled and people are redirected through London. Good spirits abound, if concerns exist about the likelihood of a meetup with the Peter/Mary group (who wisely flew Royal Air Maroc - always fly with royalty, that's what I say).
