I want the first option as an entree no more I ordered the Meat it was horrible. The aspect and the taste. First time on Swiss airlines ‘s Business class was surprise on the mediocre of the food. The seats are not as comfortable as in Emirates Brrtish airlines and Iberia airlines The service was ok not great The vanity xase is a joke Only socks, toothpaste and toothbrush. I just choose Swiss air because it was a direct flight. Next time I will rather have a flight nonstop that flying again with this company. I am a frequent flyer traveling 4 or 5 times a intraoceanic flight.but I do not think to flight for the moment again with Swiss. Great disappointment
