I recently booked a trip to Lisbon in June (which just happens to be at the same time as Euro2004) and I noticed that the aircraft I am on is a 747-400!!!!
I have booked Club Europe and therefore was able to choose a seat on the upper deck in what is actually Club World on international flights! A real treat for Club Europe passengers who travel regularly to Lisbon.
From what I can determine, 747's will be used once a day for flights on June 11,12,13,14, 21, 22, 24, 25 and July 5, 6th to boost capacity on these days to deliver Englands fans to the England games (I would imagine) which will fall around these periods. I'm not sure about other periods, they seem to be normal A319/20 or 767/757's service at other times.
I think this is most exciting as it is unusual to see the 747's on European routes, even more rare to see British Airways 747's on this route. Well done BA!
P.S: Does anyone know if the 747 would be able to park at a gate using the air bridges or would it have to park at a remote stand?
