I was only very young when Britannia began using LBA in 1976. At the time, not only did I think Britannia was a Spanish company (the significance of the name hadn't dawned on me!) but I didn't realise the 737s they used there were relatively youthful. To begin with, I guess it was BAZG, BAZH and BAZI that did the honours, so all only about two or three years old at the time. We didn't see the non-Advanced models as they couldn't reach the Mediterranean off the then 5400 foot runway. Even when I first came across later models such as BGYK, I wasn't aware how new they were. I guess BKHE and BKHF were the final pair of -200s to join Britannia, apart from BJXJ which came from Dan-Air.
