Budget airlines like Vietjet have made flying accessible to millions, but I wonder if their ultra-low fares are actually subsidized by poor working conditions and hidden fees. On a recent domestic flight, I paid nearly as much in add-ons as the base ticket, and delays felt routine. Could Vietnam's aviation market sustain full-service carriers if these budget models didn't cut corners on safety checks and pilot rest? The question is whether cheap tickets justify the hidden costs to workers and passengers alike.
