Most of the above you can get with business/upper class, depending on airline.
The bar on Virgin upper class is great unless your seat happens to be within about 5 rows of it (or further, if the real
are out) and you're trying to sleep. The crew seem reluctant to put a damper on it.
Interesting about the million pound door at T5. It p1sses me off hugely that to get to the lounge from security you have to go down one floor and drag through the nightmarish retail experience to get to the BA business class lounge even though there is a door
right there. Gets the BA experience off to a bad start.
