Same message for me
I am on UA254 DEN-ORD at 555pm Saturday 10/28 and just got this e-mail:
Important update on your upcoming flight
Important meal update for your upcoming flight from Denver
Due to limited food options in our Denver catering facility, hot food may not be available on your flight. However, snack boxes will be provided. Our Denver staff will be happy to provide you with a voucher if you’d like to purchase your own food prior to boarding.
We’re sorry for the inconvenience and hope you have a pleasant flight.
This certainly seems like a strange situation.
