We arrived at the counter 1:50 before scheduled departure. The queue took 55 minutes for us to reach the counter. We were told then we should have rushed the counter to clear the 1 hour hurdle. There was no approach by staff to warn the waiting queue to do this. We were given boarding passes and told to try our luck taking the luggage through security and try gate baggage check. We made the plane 20 minutes before scheduled departure

Free entertainment (nice selection of movies), free food and drinks (food is a bit spicy, but within reason), more leg room than expected.

At first they refused to let me in on the plane, because they misread the instructions from Dubai and thought I couldn't even be at the airport. I can't go into Dubai, but I can be at the terminal. To their credit, they realized their mistake just in time and I was able to make the flight, albeit barely, so no harm done.

This review is for return travel from ATL to MAA (Chennai, India) and back. Route: ATL-DOH: about 14.5 hrs; DOH-MAA: about 4.5 hrs; Likes: 1. Baggage check-in process was simple and easy. 2. Meal preferences was good - I'm a vegetarian and on the onward journey forgot to specify the meal preference but the crew had enough inventory to meat the requirements. 3. Every seat was provided with a small plastic pouch/packet/goodie bag that consisted of a eye mask (very thoughtful), pair of sock, toothpaste+brush (very thoughtful), hand cream. This was very useful and effective. 4. Entertainment - options were good and current.

Dislikes: 1. Online check-in wasnt easy; towards the end of the process, there is an option to email the boarding pass but this never worked. Not sure if this is something to do with the browser (tried with Firefox, Opera) 2. It would have been good, as part of the online check-in, if the users reminded to specify the meal preferences, etc. I forgot to specify the meal preferences but thankfully the crew had enough of what I wanted. 3. Take a relook at the packaging of the toothpaste tube in the goodie bag. It was sealed in such a way that it was difficult to open it w/o a sharp object. This should have been easier. 4. Seats were the worst part - poor legroom. Worst, the seat cushion is the worst. I think it was just a fabric over a metal seat with minimalist of cushion. ATL to DOH leg was the worst (and the longest leg of the trip). Unless you have open seats next to you it would be a back breaking and painful trip. Seat comfort wise, I would rate Qatar as the worst. Luckily on the return leg (DOH-ATL) next two seats to mine was empty, so was able to stretch and sleep well. DOH-MAA or MAA-DOH seating was little better (think its a older plane; newer planes have worst seats) 5. The website was damn slow while accessing from overseas. Even in the US, at times the website hangs-up, freezes or spins often. 6. Food was ok -dinner and lunch but minimalistic; I didnt see any specific breakfast menu or any coffee served separately (was part of beverage option during lunch or dinner) 7. There was no alert, communication, notification, reminder of upcoming trip via email or text, etc. Many airlines does this very often but Qatar was totally silent on it (they did have my email during checkin). Not sure why.

My checked bag did not arrive at my work city of Singapore. It took 2 days to be brought to my hotel despite my being told they would be on the next flight. I arrived back in Denpasar yesterday and, again, my bags are lost and I again I was told they would be on the next flight. I still do not have my bag. Seems to be a pattern with Malaysian Airways and I will avoid them in the future, Also, I left my Ipad plugged in at the Premier Lounge in Denpasar and realized it as I was boarding the plane. The Malaysian Air boarding staff got on radios and appeared to try to help by telling them to put aside for pick up upon my return. Yesterday, The Premiere lounge said they did not have it despite my name, email and phone number being written on the Ipad. Between Malaysian Air and the Lounge and their lack of concern and professionalism it was not a good trip. As One World Emerald member, I steer a lot of business towards these One World Airlines. I expect better treatment.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
