This is yet another example where contacting BA is - unfortunately - more likely to give you wrong information than FT. The person who wrote it may have never been on an aircraft in his/her life, whereas this forum is jam packed with people who fly BA day in, day out. I guess you wanted more reassurance than the information here, but you wouldn't be the first to end up even more confused. It should not happen like this. And I would be fairly sure my earlier information is correct. That said, of all the misinformation I have seen coming out of that particular service centre - and we can all accurately guess which one it is - this must be an absolute classic of an answer. Forward it on to YouFirst if I were you, they will have a good chuckle about this in Manchester!

If you want somewhere quiet in SEA beforehand then there are all sorts of nooks and crannies to that airport, with good views, and rather more spacious than the 2 BA rooms.
