Short answer — from Egypt the cheapest reliable way right now is to book a seat on a regional low‑cost carrier (Jazeera Airways or Air Arabia Egypt) or a discount nonstop with EgyptAir when there’s a sale. These carriers frequently show the lowest one‑way/economy fares Cairo (CAI) → Kuwait City (KWI). (jazeeraairways.com)

What to expect (current price examples)

• Jazeera and Air Arabia Egypt are currently showing some of the lowest published fares on the CAI–KWI route (examples found in searches: Jazeera fares advertised from ~EGP 4,700; Wego lists lowest near EGP 2,796 on some dates). Prices vary a lot by date and seat availability. (jazeeraairways.com)
• EgyptAir also runs competitive non‑stop fares regularly and sometimes undercuts LCCs during promotions. Google Flights shows EgyptAir, Jazeera, Air Cairo, Nile Air and others with deals on different dates. (google.com)

Fast steps to get the cheapest ticket right now

1. Be flexible on dates: mid‑week and off‑peak dates are usually cheapest.
2. Check aggregator sites (Google Flights, Skyscanner/Wego) for a quick price calendar, then book directly with the airline if the price matches. (Aggregators help find the cheapest day; book on the airline site to avoid hidden fees.) (google.com)
3. Compare nonstop LCCs: Jazeera Airways, Air Arabia Egypt, Air Cairo and EgyptAir — sort results by price and total cost (baggage fees included). (jazeeraairways.com)
4. Use incognito/private browsing and clear cookies if a fare seems to rise after repeated searches.
5. If you can travel from nearby airports (Alexandria HBE, Sphinx SPX, or fly a cheap connection via a Gulf hub), check those too — sometimes a short domestic leg + cheap regional flight is cheaper overall. (jazeeraairways.com)
