Short answer — as of today (Thursday, October 30, 2025): the cheapest option from the UAE to Kuwait right now is usually a nonstop Sharjah (SHJ) → Kuwait (KWI) on Air Arabia (one‑way fares seen from roughly AED 197 / ≈€47). If you’re leaving from Dubai, low‑cost Jazeera Airways and flydubai frequently have the next-lowest one‑way fares (from about AED 329–450). (ae.Trip.com)

What to do to get that cheapest fare (quick checklist)

• Check Sharjah (SHJ) → Kuwait (KWI) on Air Arabia first — they operate frequent nonstop flights and currently show the lowest one‑way/round‑trip prices. Example listings and recent fares available on Trip.com / fare comparison pages. (ae.Trip.com)
• If you’re in Dubai, compare DXB → KWI on Jazeera Airways and flydubai — both show very competitive one‑way fares (Jazeera often ~AED 329–420; flydubai ~AED 450). (jazeeraairways.com)
• Use a flight meta‑search (Skyscanner/Google Flights/Trip.com) with “flexible dates” turned on to find the cheapest day within ±3–7 days. Trip.com listings already show many low‑priced dates. (ae.Trip.com)
• Compare one‑way vs round‑trip pricing — sometimes two one‑ways on different airlines are cheaper than a round trip.
• Book directly with the airline if the price matches the meta‑search (often easier for changes/refunds); otherwise book through a reputable OTA shown in the search. Always check baggage fees — low fares often exclude checked baggage and seat selection.

Practical tips to lock the lowest price

• Be flexible on departure airport: Sharjah (SHJ) often beats Dubai (DXB) for low‑cost carriers to Kuwait. (zbordirect.com)
• Search in incognito/private browsing or use multiple OTAs — sometimes prices vary by site.
• If you need to travel within 24–72 hours, expect prices to be higher; last‑minute low‑cost seats occasionally appear but are unreliable.
• Check baggage/seat/change/cancellation terms before payment — the headline fare can climb after add‑ons.
