So, given the airlines' propensity for shrinking legroom, will I be able to tell the inconsiderate fellow traveler sitting in front of me not to recline his/her seat into my face, meal, etc.

And, more importantly, will crew members back me up.

After all, I did pay for my seat and implied comfort their ads tell me about.

Usually, crew back up the recliner which is totally inexcusable.
