I want to recommend Etihad airways Since it is very comfortable and cheap airway.
I traveled from Abu Dhabi airport to Guarulhos Airport of Sao Paulo. The flight was very long, it was for about 17 hours. But I really enjoyed travelling through this airways and I loved it. The staff is really very cooperative. The food is really delicious and Arab style. They provide Halal food for all. At the end of the journey, they apologise for the non-Muslims for serving Halal food.
We were travelling to Brazil so we had a lot of Portuguese speaking people. So the staff also had an African Portuguese speaking girl.
I really enjoyed this jet aircraft. I think it was always at the time. The system for luggage at the airports was really appreciatable. They really want to help their passengers. They also guide their passengers with the entry information for the destination.
I loved it and I would want to travel by this airways again.
Thanks
