I've flown with most of the major airlines and Emirates are the best in my own opinion They're are always my first choice if I can afford them. The aircraft are very clean and new, if you're lucky you might even get a A380 which is quite simply superb, especially if you're in Business Class as I was a few weeks ago The staff are extremely friendly and helpful, the food's good. I've flown long haul with them 3 times and can't fault them. The only thing I don't like about Emirates is Dubai Airport....it's massive and the smoking lounge is about 15 minutes away from the main entrance
Have a great trip
