I am sure they sells them all over but personally that is the only place I have ever seen them.

If you have seen them elsewhere,please tell me where.

Try googling the full name on the label, <i>e.g.</i> <b>&quot;darcy's exquisite lemon bon-bon drops&quot;</b> (including the quotes).

I always loved T-4 but now we Californians who fly on BA must use T-1. There aren't as many nice stores there and Harrod's, though in one large area, doesn't seem as nice as it does in the 3 or 4 areas it has in T-4. I like the large, deep yellow signs at check-in. Hope that we live long enough to see T-5!

I may have found a place out of Portland Oregon that sells them. All the other places were in the UK.

From practical points, the fastest passport control (aside from HK and S'pore), thanks to IRIS scheme and a separate immigration queue for visa holders (often the shortest, officers wave you over non-visa holders).

From amenity perspective, BA business lounge--far better offerings of foods and drinks, a nice change from junks offered at other business lounges.
