Short answer — from Doha (DOH) the cheapest, most reliable carriers for short/weekend trips nearby are typically:

• Air Arabia (Sharjah and other UAE routes) — low-cost, frequent DOH–SHJ service and often the lowest fares for quick UAE getaways. (airarabia.com)
• flydubai (Dubai) — a budget airline with many daily DOH–DXB flights and competitive one‑way/return offers for short trips. (flydubai.com)
• SalamAir (Muscat and other Oman routes) — an Oman-based low‑cost carrier that runs multiple DOH–MCT flights useful for overnight/weekend breaks. (wego.qa)
• Oman Air (GCC promos and frequent DOH–MCT/Oman links) — a full‑service carrier but often runs regionally cheap sales that make short breaks affordable. (timesofindia.indiatimes.com)

Why these are good for weekend getaways

• Short flight times (1–1.5 hours to UAE/Oman) mean you get more time at destination. (flightsfrom.com)
• High frequency (daily/multiple daily flights) lets you pick Friday–Sunday or Saturday–Monday combos without big price penalties. (airarabia.com)

Typical cheap fares (examples you can expect)

• Air Arabia: very low one‑way fares on DOH–SHJ reported in booking engines (examples ~USD 70–130 one‑way/round‑trip depending on date). (trip.com)
• flydubai: published lowest one‑way fares around QAR ~750 and round trips QAR ~900 on some months (prices change by season). (flydubai.com)
• SalamAir/Oman Air: Muscat routes often show low‑cost one‑way options and periodic flash sales (prices vary). (wego.qa)

Quick tips to get the best weekend deals

• Be flexible on departure/return days (Friday vs Saturday return can change price).
• Book on the airlines’ own websites (Air Arabia / flydubai / SalamAir / Oman Air) — LCCs often have lowest fares direct. (airarabia.com)
• Check flash sales and “lowest fare” calendars (these airlines run regional promos regularly). (timesofindia.indiatimes.com)
• Compare one‑way pricing (mix-and-match airlines) — sometimes outbound on one LCC and return on another is cheaper.
• If you travel very light, choose bare‑fare/basic fare and add baggage only if needed.

If you’d like, I can:

• Search live fares for a specific upcoming weekend (I’ll check exact prices and times from DOH to a few nearby cities); or
• Give suggested 2–3 itineraries (timings + cheapest carrier) for a Friday–Sunday or Saturday–Monday trip.
