Lovers of tomato juice are a small camp, but a vocal one. And they're furious that United Airlines has replaced their beloved Mott's tomato juice with Mr. and Mrs. T Bloody Mary Mix on all flights under four hours, which includes most of its domestic runs. United said these changes are part of efforts to “streamline” its food service, the Chicago Business Journal reports.

The stealth substitution has fueled a rebellion among loyal tomato juice fans, as The Week points out.

There is some truth to the claim that tomato juice tastes better on flights. One study revealed that the noise level on an airplane affects our perception of taste, making savory or umami flavors more delicious. Another industry-funded study said the air pressure and humidity levels make bolder drinks seem more appealing.

Premium and economy passengers flying United can also say goodbye to Sprite Zero, Jim Beam, Courvoisier, and Amaretto, which were cut from the menu. And although airlines are not exactly known for their cuisine to begin with, passengers will likely start to see a difference in the types of meals being offered. The Chicago Business Journal writes:

"The reduction in food being offered in many instances in first-class and business-class cabins is not insignificant. Hot breakfasts are being replaced on some routes with only fruit plates and muffins, and more substantial lunches are being switched out for wraps and chocolate slabs."

The airline has said it is "monitoring customer feedback."
