Midhat,Sept 2026

ADL - DOH

Hostess called Vina, from Adelaide to Doha on the 25th of September was very rude and racist. Ordered apple juice, she mentioned was not available. A passenger 2 rows ahead was offered apple juice. Asked her to ask the passenger on the chair in front of me to put straight to be able to eat my food, she said you can put yours back, which I did. On the next meal service, she came asking rudely to put our chair straight! Ignoring us completely when serving refreshments, despite being very thirsty. Unprofessional, rude service was not expected to see this on Qatar airways.
