After years of financial hardship, US carriers at last have the cash and stability to invest back into their products. Airlines plan to spend over $2b on upgrades to cabins, lounges, and other improvements in the short-term. While for most of us on here this is not news in itself, as we all know about a lot of these improvements, it's an important step for US carriers, who have fallen behind during the last decade.
Personally, I'd like to see Delta's new Seattle lounge with the "floor to ceiling" windows. My guess is American's fireplace in San Fransisco is not wood, but gas?
Besides what's mentioned in the story, what other surprising improvements have you seen flying around the country?
