Hello all, a friend and I will be traveling from Los Angeles to Buenos Aires. We have our flights booked for departure from LAX to AEP. We arrive on November 4, 2025. Our plan is to catch a flight from Buenos Aires to Iguazu Falls in Argentina. I note that there are two airlines with multiple flights to Iguazu and from Iguazu to Buenos Aires: JetSmart and Flybondi. There is a third, which is Aerolineas Argentina. The reviews for both JetSmart and Flybondi give me pause; they are primarily negative. However, I recognize that when people are frustrated and have a not-so-good experience, they mostly share their negative reviews. I trust this forum and the experienced people leaving comments/advice/recommendations. The flight rates are very good for both JetSmart and Flybondi. However, would you suggest spending the extra money for Aerolineas Argentina? Thank you

Statistically Aerolineas is the most reliable of the three though I have still experienced schedule changes & cancellations . BA - Iguazu will have multiple flights per day so choosing the most convenient time is as important especially if on a tight schedule. An early flight there and late flight back can reduce the # of nights you need to stay there. A delayed flight can screw up your plans significantly!

the # of flights per day with each airline is also important. If one is cancelled they can put you on the next.

i would allow half a day to visit the Brazil falls and a full day for the Argentine falls

Airlines in Argentina are notoriously rather unreliable

If you need reliability and comfort, I would choose Aerolíneas Argentinas - flights tend to be on time with somewhat better service. JetSMART is okay if you can be flexible and want to save money, but watch out for extra costs. Flybondi can be a bit too unpredictable if your schedule is tight and should be avoided.
