Hunger struck somewhere over the Indian Ocean mid a 14-hour Etihad flight from Sydney to Abu Dhabi. Requesting a snack, I was handed a colourful brochure bursting with delicious options. Mmm, ‘Gourmet Himalayan Pink Salt Chips’? Yes please! But wait, what is this AE8? (AUD$3.15). Since when do long-haul full-service carriers charge for snacks? As of now.
