- Viva Aerobus (Mexico): Very low fares, but frequent delays and limited support.
- Pegasus Airlines (Turkey): Cheap but often criticized for punctuality and hidden costs.
- FastJet (Africa): Patchy reliability and frequent cancellations.
- Some small start-ups: Always research safety records before booking with new or unknown carriers.
Tips for Flying Budget Airlines in 2025
- Travel light: Fees for checked bags can exceed ticket prices.
- Check airports: Budget airlines often use secondary airports far from city centers.
- Arrive early: Strict check-in cutoffs mean missed flights if you’re late.
- Read the fine print: Always check what’s included in your fare.
- Bring food & water: Onboard snacks are expensive.

Final Thoughts
Budget airlines in 2025 are more innovative and widespread than ever. While Ryanair, EasyJet, Southwest, AirAsia, and IndiGo consistently deliver value, others like Frontier or Viva Aerobus often frustrate travelers with hidden fees and poor reliability.
If you pack smart, plan ahead, and accept fewer frills, you can fly the world for a fraction of traditional fares. Just remember: with budget airlines, preparation is everything.
