We do it every single trip (4 trips in last 4 years).
Tips: vacuum seal if you can (portioned out into meals), freeze it, pack in a Polar Bear cooler. Fill the cooler with frozen meats, cheese, etc.k Stays frozen for 48 hours. Some trips we've been charged a "tax" (never more than $10), some trips no charge. Seems discretionary :-)
We mainly do this for the ease of meal prep - no messy steaks or chicken leaking in the fridge, easy to pull the "burgers for night #2" when it's time to prep, and I can precook things like taco meat, sausage for pizzas, chicken for cold salads, etc.
