There was no WiFi connection all through the 6-hour flight even though we were made to believe there will be when purchasing the tickets. Also there was no toilet around the Premium seats. One had to walk all the way back to the main economy cabin to use toilets. Why pay so much more for premium when you will be made to use main economy rest room facilities?
