Digital Library of Mathematical Functions, section 9.7 gives the Airy function asymptotic expansions. Equations 9.7.5 and 9.7.7 give the positive-argument exponential forms; equations 9.7.9 and 9.7.11 give the negative-argument oscillatory forms. Their leading terms determine the factor two and phase shift in the Airy turning-point connection formula.

Cited passage: abstract, general averaged variational formulation for slowly varying wave trains. The simple linear-wave example in the concept articles is derived explicitly there rather than attributed to an uninspected page of the paper.
