I was cramped, the staff never came around with water and always seemed grumpy. Not your typical Fijian hospitality at all. The plane was tiny and after already flying for 11hrs to then be cramped and uncomfortable. Dehydrated and seated in what felt like an unpadded seat for another 3.5hr flight, was terrible.
