I thought another interesting aspect of the article was the description of the meals along the way, notably the meal at the terminal in London before departure. What plain food out grandparents "enjoyed" at that time, and for the time it probably cost a bomb.
Food in 1951 wasn't long out of rationing, and such fare was quite a treat! ISTR that chicken was seldom on the menu at home: we certainly looked forward to it as the main course for Christmas Dinner
