 I do actually have a problem with saying that the claim is explicitly false.  I follow this issue through multiple sources and the most that can be said so far is that the hypothesis is unproven.  (Like many "natural" remedies, there is no funding for the kind of extensive double-blind studies needed to conclusively prove the issue one way or the other.)  My concerns are lessened by the the attribution but we should not err with overstrong statements on either side of the argument.  In the meantime, here are a few actual studies that have tried to find hard data on the subject:
 Int Arch Allergy Immunol 2011;155:160–166  (DOI:10.1159/000319821)  Birch Pollen Honey for Birch Pollen Allergy – A Randomized Controlled Pilot Study, Saarinen et al
 did find a 60% reduction in symptoms for this one specific allergy
 2002 study at University of Connecticut (sorry, can't find the cite tonight) 
 found no significant differences among sufferers of allergic rhinoconjunctivitis (non-specific to allergen source)
 Incidentally, the Mayo Clinic calls the case for allergen relief "unclear" (a grade of C).  They give that same grade for the other medical uses of honey - a fact which may be relevant to the discussion below.  See http://www.mayoclinic.org/drugs-supplements/honey/evidence/HRB-20059618.
