Lounges are not only for business-class tickets. Priority Pass and LoungeKey memberships attach to premium credit cards or sell standalone annual plans — verify which lounges exist at your departure airport before relying on them.
Single-visit passes via apps like LoungeBuddy or airline day passes suit occasional travellers. Some lounges sell walk-in access for €30–50 — compare against airport restaurant spend during long layovers.
Arrive early but not absurdly — peak hours mean capacity holds. Showers exist in major hubs; pack a change of shirt for long-haul turnarounds. Quiet zones beat buffet noise for work.
Build layovers intentionally when hunting fares — SnagAFlight compares hub options where a four-hour connection unlocks lounge value without overnight hotel costs.
