On a LAX-JFK currently in J. No hot meals, do have soda, champagne, and OJ pre-departure. Did offer some sandwich wrap or a salad (prepackaged). While paying for another flight with a voucher, the ticket agent said it should resume back to normal by the end of the week. Did get an amenity kit on my flight unlike some others. Voucher I got was $50, but tweeted telling them they should at least offer free premium drinks in the Admirals clubs that are open, given this nightmare.
Tried to get a free premium drink in the Admirals club but got shot down (I tried - figure EXP plus J plus messed up food service would work).
Also, no Bose headsets in J?
If flying coach, you pick your snack/drink in the jet bridge.
