Steven Slater Flies Again ... But Not JetBlue

Former JetBlue flight attendant Steven Slater is taking his business elsewhere -- dude boarded a non-JetBlue aircraft today ... and no, he wasn't seated anywhere near an emergency exit.

TMZ has obtained photos of Slater catching a US Airways flight this morning from Charlotte, North Carolina to New York City -- where he's required to appear in Queens County Criminal Court tomorrow over his infamous post-flight meltdown. 

As we previously reported, Slater -- who faces 7 years in prison for charges including reckless endangerment -- agreed to voluntarily admit himself into a mental health program as part of a possible plea deal.

We'll be covering the case ... so stay tuned.
