Below is a practical, region-focused guide to which airlines commonly operate direct (non‑stop) flights to popular holiday destinations — tailored for a traveler based in Saudi Arabia (Riyadh, Jeddah, Dammam) but broadly useful elsewhere. Note: routes and seasonality change, so use this as a quick reference and check schedules when booking.

Europe (short–medium haul leisure hotspots)

• Saudia (Saudi Arabian Airlines) — direct to London, Paris (seasonal), Istanbul, Milan, Rome.
• British Airways — London (from Riyadh/Jeddah).
• Turkish Airlines — Istanbul (major hub with onward direct links to many European holiday cities).
• Lufthansa — Frankfurt, Munich (good for transfers to Mediterranean resorts).
• Air France, ITA Airways (formerly Alitalia) — Paris, Rome, Milan respectively.

Mediterranean / Aegean beach destinations (Greece, Cyprus, Turkey)

• Turkish Airlines — Istanbul and many direct seasonal flights to Antalya, Bodrum, Dalaman.
• Pegasus Airlines — Istanbul and many Turkish holiday-city routes (often seasonal).
• Cyprus Airways / other carriers — Larnaca, Paphos (seasonal charters).
• Saudia and other Middle Eastern carriers may operate seasonal charters to popular Greek islands.

Red Sea & Egypt (very popular from Saudi)

• Saudia — multiple routes to Sharm El-Sheikh, Hurghada (seasonal/charter).
• EgyptAir — Cairo, Sharm El-Sheikh, Hurghada.
• Flyadeal / low-cost regional carriers — sometimes run direct leisure flights to Red Sea resorts.

Gulf & Arabian Peninsula (short breaks, beach/island getaways)

• Emirates — Dubai, direct and very frequent (great for short trips).
• Etihad — Abu Dhabi.
• Qatar Airways — Doha.
• Oman Air — Muscat.
  These carriers also offer seamless connections onward to Indian Ocean resorts.

Indian Ocean & Tropics (Maldives, Seychelles, Mauritius)

• Saudia — direct seasonal flights to Male (Maldives) at times; also charters.
• Emirates / Qatar Airways / Etihad — frequent one-stop service (often via Gulf hubs); sometimes seasonal direct charters exist from Saudi.
• SriLankan, Air Mauritius, Seychellesair — operate direct routes to those islands from regional hubs (often require a connection from KSA).

Southeast Asia (Thailand, Malaysia, Singapore, Indonesia)

• Saudia — direct to Kuala Lumpur and sometimes to Jakarta (seasonal/limited).
• Singapore Airlines — Singapore (usually via a direct service from Riyadh/Jeddah on select periods).
• Thai Airways / Oman Air / Emirates — mostly one-stop via hubs; direct services may be seasonal.

United States & Canada (long-haul holiday cities)

• Saudia — Riyadh/Jeddah to major U.S. gateways (e.g., New York, Washington, Los Angeles) — check current routes.
• United, American, Delta, Air Canada, British Airways, Lufthansa — operate direct transatlantic flights from nearby hubs (London/Frankfurt) or sometimes direct from Middle East gateways.

Budget & Charter carriers (seasonal holiday routes)

• Low-cost carriers (e.g., Flyadeal, Wizz Air Abu Dhabi, Pegasus, Nile Air) and tour-charter operators often launch direct/seasonal flights to beach resorts and holiday islands during peak seasons — check for charters to Greece, Turkey, Egypt, Maldives.

How to use this guide effectively

• For travel from Saudi Arabia: check Saudia, flynas/flyadeal (low-cost), Emirates, Qatar Airways, Turkish Airlines and EgyptAir first — they cover most popular holiday markets either nonstop or with short connections.
• For island/tropical holidays (Maldives, Seychelles), look for seasonal direct flights but be prepared to connect via Dubai, Doha, or Istanbul.
• For Europe in summer: many carriers add seasonal non‑stop routes; for winter-sun (Canary Islands, Egypt, UAE) look for year‑round and charter services.
• Always verify: flight availability, exact non‑stop status and seasonality can change — confirm on the airline’s site or a flight search engine before booking.

If you want, tell me a specific origin airport (e.g., Riyadh or Jeddah) and a destination or region (e.g., Maldives, Greece, London) and I’ll list which airlines currently fly direct and typical flight times.
