I had one of the best experiences ever. On this flight, I was going through a miscarriage without knowing, and one of the crew members, 'a woman,' made sure to go out of her way to help me overcome this unknown event. She was kind and took the time to have a 1:1 with me to ask me what was happening. She shared she had to kids and understood perfectly fine what I could potentially be going through. She was attentive to my husband and me the whole way since it was close to 11 hours of pelvic pain and emotional stress since I did not know what was happening to me. Unfortunately, I was going through so much that I did not even have the dignity to ask her for her name, but if I saw a picture of her, I would recognize her. Air Tahiti has been one of the BEST flights I have ever taken.
