No.

If you even so much as hint that you don't want any food, the flight attendant will call both the pilot and co-pilot and they will promptly yet swiftly storm out of the cockpit and duct tape you to your seat.

Then, the 3 of them will take turns jamming food down your throat as your loved ones sitting beside you shriek in horror.

Once the whole ordeal is done and the plane has landed, you will be escorted off the aircraft like the little bitch you are, and will get your ass handed to you by the FAA, DOD, FBI, CIA, NSA, DEA, KGB, FSB, NYPD, LAPD, SFPD, MBPD, USN, USAF, USAA, USMC, USCG, USDA, DHS, DOR, DMV, DOE, DOL, ICE, EPA and my personal favorite, the Department of Housing and Urban Development.

Yes, every 3–4 letter accronymed federal agency you can think of will kick the shit out of you for your insolence and utter disrespect of rejecting a crappy in-flight meal that has been pre-heated in the same microwave without being cleaned since the late 1980’s.

Once you're done eating fists, the flight attendant whom you had the nerve to reject will take you to court, win full custody of your 3 children, take your home, boat, car, condo in Miami, timeshare in Barbados, membership to your gym, membership to your country-club, your golden tooth, your other kidney that you're not really using, and have you pay an exorbitant alimony of $10,000 a month.

You will then be branded a terrorist, never be able to fly again let alone reject another in-flight meal, and your life will come crumbling down on you.

All because you said “no thank you” when you were offered an in-flight meal.

You poor bastard.

Now for the real, obvious, sans-sarcasm answer:

Of course you can. If you politely decline, the flight attendant will store the food and carry on with her job.

No one is forcing you to do anything, especially accept a meal.
