"select aircraft" suggests that the 787 retrofit may not be happening as "soon" as originally intended.
The gel pillow is an interesting one. I love them. However, on ICN-SFO today, in the rear cabin of 18 seats, I was the only passenger who requested and used a gel pillow. 3 passengers requested pajamas, and 2 asked for the mattress pad. I'm including myself in those numbers. I realize many people may not know about them, but the GS seated next to me was fully aware and didn't consider them worth asking for.
