Qatar Airways was a top choice for travel in the past, now their top-ranking is a thing of past as well. Their quality is deteriorating fast. Their seating is smaller to squeeze more seats in smaller area, leg room is now smaller as well. All of their crew used to provide top-notch service but now your experience will vary from one crew member to the other. For food many a times they will offer you two options and then will say 'oh we ran out of the other option'. For drink options sometimes they will skip your row completely.
