Until last autumn, Wu was a software developer based in Chicago, but he decided to quit his job and sell his home to embark on full-time travel for a couple of years.
"I love to travel (I flew 102,000 miles in 2018 alone) so over the years, I developed a decent collection of airplane food pictures and I never knew what to do with them," Wu told Business Insider.
He originally started the Instagram account to make fun of his friend's food blog.
"It really started as a joke but it just really took off to my surprise," Wu said.
"People seem to really like the idea of the account, maybe because it's unique and people are curious. And maybe a lot of other people probably also take pictures of airplane food when they travel like I do but never know what to do with them, so I'm giving them a channel to showcase."
At the beginning, Wu was only sharing his own pictures.
However, a month after starting the account, people started sending him their own pictures of airplane meals — he now receives so many he can scarcely keep up.
A private jet picture is the most popular one.
"The most liked picture was someone's private jet picture [above]," Wu said. "It's not necessarily the best but I guess maybe it was popular because it was more unique and people are curious about private jets."
The second most popular is of Korean Air prestige class.
"It's good but not necessarily the best," he says, but admits that his newer pictures are getting more attention purely because his following has grown.
If you base your airline choice on the food served, Wu's Instagram may help you make a decision.
