My experience with this flight was extremely negative and resulted in serious financial and personal consequences. The flight departed with a significant delay, which caused me to miss my international connecting flight. As a direct result of this delay — which was entirely beyond my control — I was unable to reach my final destination on time, causing me to lose a previously scheduled hair transplant surgery that had been arranged months in advance. This was not a minor inconvenience. The surgery involved: • A reserved operating room • Medical and technical staff scheduled specifically for that date • Surgical instruments prepared in advance • Strict scheduling that does not allow for easy rescheduling Due to the airline’s delay and poor handling of the situation: • I lost already paid international flight tickets • I was forced to purchase new tickets, incurring duplicate expenses • I spent over six additional hours in airports, under stressful conditions • I incurred unexpected costs for meals and transportation • I lost a medical opportunity that cannot be easily recovered, along with the emotional distress associated with it Although the airline covered one night of hotel accommodation, this did not address the real impact of the delay, nor the significant damages caused by missing a critical medical procedure. The lack of punctuality, planning, and effective solutions reflects a serious lack of responsibility toward passengers, especially when international connections and time-sensitive medical commitments are involved. I do not recommend this airline for travelers with important schedules, medical appointments, or critical connections. In my case, the delay did not merely cause inconvenience — it resulted in the loss of a surgery and substantial financial damage.
