The flip side of this argument could be that an airline that spends all its money on making an airplane look cosmeticly nice might not be spending its money on the things that matter most. I’d far rather fly on a safe but scruffy looking airplane, than I would fly on one that looked pristine but which hadn’t had the requisite behind-the-scenese maintenance done on it.
FWIW, I’d fly on that airplane.
