Airline reviews

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

Great food and good entertainment options for the long flight.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.
