The brand they use is Philosophy.
I thought the hand soap smelled really nice too! Thought I was weird and the only one

For my flight, the foaming hand soap was Philosophy Pure Grace. However it could potentially be any of the Grace line fragrances. If it smelled very clean and light, kind of like laundry, than it was Pure Grace.
The face wash would be Philosophy also, but I could not tell you which fragrance exactly.
