I went on business class on EK to DXB (from IAH) and then onwards to India but economy on Qatar to DOH (from IAH) and then to India.

For Apples to Apples comparison, I enquired with my friends who travelled both in business and economy on EK and QR.

EK: Business class is excellent. Spacious, nearly flat bed, excellent IFE and excellent food, free limo pickup from my home (my house is nearly 40 miles from IAH).

But I heard that economy is cramped with 10 seats in a row (3-4-3) in 777. But IFE is supposed to be good even in economy and food is pretty good, good liquor service even in economy.

DXB is a good airport to connect with all amenities.

QR: Economy class is average. Food was average to below par. They have only one kind of beer. Seating is better than EK (3-3-3 on 777) but when the seat in front of you leans, you have to lean too and it is difficult to view the monitor when the seat is leaning to the maximum. IFE was good. No limo pickup for business class.

Main advantage is QR is much cheaper than EK.

Business class on QR is not as good as EK, but IFE is pretty good.

DOH is not a good airport to connect, cramped, no jetways, very few food choices at DOH.
