As of now they will not let you take Boost or similar on board, but might let you take a prescription formula (such as Nutren) but each can would have to be labelled with your name and match your boarding pass. No Oral Balance or other gels or liquids unless less than 100 ml.

I wrote to the TSA on their comment page about this and I urge others to do the same. Perhaps OCF and other head/neck cancer support and information organizations need to get on TSA's case. Also, oral cancer patients are not the only ones who might need liquid nutrition during a long flight, my mother used it during her leukemia treatment. Perhaps as a quick fix airlines could carry some cans of Boost or Ensure but that does not solve the "articifical saliva" problem. I will post when (or if) I hear back from TSA.
