A record-breaking heat wave coming to the West Coast could bring major flight delays with it, 9News reported.

Temperatures in Phoenix are expected to come close to the all-time high of 122 degrees on Sunday and Monday for the first time since 1990, 9News said. Temperatures in Denver are expected to linger near the low 100s. Planes have issues operating at such temperatures, as wings and engines tend to struggle during take-off, NBC aviation analyst Gregory Feith told 9News. VIDEO
