Time for a beach getaway! Great sale on Delta nonstop, round-trip flights from Denver to San Diego. Availability February – March, return dates extend up to July. This flight deal also works vice versa if you live in San Diego and want to see Denver. All round-trip flights include free carry-on. Advance seat assignment is extra. Book quick, this fare won’t last!

This fare is Delta’s “Basic Economy fare” which does not allow seat assignment until check-in. This fare still earns SkyMiles and allows free carry-on bags. Carrying a Delta co-branded Amex card helps you beat Delta Basic Economy.
