In this paper, we discuss Airy solutions of the second Painlevé equation (P II ) and two related equations, the Painlevé XXXIV equation (P 34 ) and the Jimbo-Miwa-Okamoto σ form of P II (S II ), are discussed. It is shown that solutions that depend only on the Airy function Ai(z) have a completely different structure to those that involve a linear combination of the Airy functions Ai(z) and Bi(z). For all three equations, the special solutions that depend only on Ai(t) are tronquée solutions, i.e., they have no poles in a sector of the complex plane. Further, for both P 34 and S II , it is shown that among these tronquée solutions there is a family of solutions that have no poles on the real axis.
