I'm planning to travel to a friend's wedding in Spain later this year and looking at taking some time before and after it in some Europrean cities (I was thinking initially HKG-LHR-PMI-BCN/FCO/MAD-HKG) but I figure I'd see if there are any insights as if there's a better deal from any particular hub city (i.e. HKG-MAD//LHR-HKG, for example) that might be cheaper (especially as we are traveling for the whole family).

Also, query if you think it is best to get the [LHR/BCN/MAD/FCO]-PMI ticket separately or just get it as a BA/Iberia ticket as part of the multi-city purchase?

Thanks!
