Everything went smoothly, but when I have read their contract, I've found they are agree to pay no more than $8 per kilo (about two pounds) in case your luggage get lost. And the food ("Enjoy your meal") is a junk.
Look for promotions: Most airlines have special offers almost all the time. These offers are usually valid only for specific destinations and for specific dates (or days of week). If you are flexible on dates, check "what is on sale now", to get the best price! If there is no discount on your desired route and if your dates are flexible, you can wait for 2 to 4 weeks for a promotion on that particular route.
