It's too bad they couldn't have added some windows or a skylight to let in some natural light.

Yes, certainly that is one of the downsides, but the location - in the middle of the building on the lower level for the nearby bus set-up for most LIN services - means they are some distance from a natural light source.

Yes, really sorry for the confusion, I got confused with the old FCO arrangement prior to the refurbishment!

So I was there Sunday and it seemed virtually identical with two changes I noted during my quick visit: there used to be newspaper tables as you came in, in a fairly poorly lit area. It is now lighter with many little tables and chairs instead (like those in the fourth photo above). And there was indeed some hot food, perhaps the same batch of eggs in the penultimate photo has been topped up from time to time.

The BA counter as you come in has not been changed and there is little evidence of much change in the terminal (beyond perhaps a new escalator when you descend to the level of the BA gates where there used to be only stairs). But there are signs around the airport indicating that there are another five months to go until things will be finished inside. The experience of the bus to the plane and climbing the stairs in the rain was unchanged.

Adding my experience after my flight back home from the hols yesterday.

Loved the new furniture as the previous one was most outdated, although the lounge design and colour palette itself did not project the feeling you would expect from a "owned" airline lounge. In other words, it did not feel like BA. It is indeed new and fresh, but it lacks character IMO.

I appreciate little can be done to catering etc. being an outstation, but decor and design are 100% within the control of BA and it seems to me they are not making an effort to stand out. Bit odd.

Maybe I’m wrong but aren’t most usb chargers 100-240V?

You're not wrong, but perhaps Jagboi was simply saying North American 120V as a shorthand and commonly understood way of referring to the physical form factor of the socket. It is probably a lot more meaningful to most people than saying e.g. a NEMA 5-15R outlet!

i.e. it was the form factor that was important and allowed them to plug their charger in directly, not the actual voltage per se.
