Oma Premium Lounge is the Priority Pass room at Ponciano Arriaga International (SLP). Priority Pass places it airside after Security Control — turn right to the end of the waiting area. Hours on PP and OMA SLP (research day 2026-09-19): 05:00–20:00 daily; max stay 3 hours; children under 5 free; boarding pass required.

Verdict is worth-it for a Central Mexico OMA secondary with an early 05:00 open and complimentary capped drinks — but it is not an overnight lounge.
