DEL - JFK

I recently flew AA’s business class from Delhi to New York, and while the experience ticked the basic boxes, it didn’t quite soar. - Dining: I opted for the vegetarian meal, which was… fine. Not memorable, not offensive—just hovering in the realm of “meh.” The menu could use a refresh with more thoughtful, flavorful options. - Seating: AA seems to be chasing quantity over quality, squeezing in as many business class seats as possible. Yes, they’re lie-flat, but noticeably narrower than what you’d find on other international carriers. Comfort was passable, but not premium. Overall, I’d call it “business class lite.” It gets the job done, but lacks the finesse and attention to detail that elevate a journey. A few strategic tweaks—better food, more spacious seating, and a touch more hospitality—could make a world of difference.
