What flight should I take to Europe?

Budget came as one of the major decision makers for us. But of course comfort level was taken into consideration.

Cheap flight to Europe?
For flight, the first and foremost we looked at was the price. To give a little bit overview of our psychography: we are young travelers who prefer to travel by budget airlines on usual basis only because of the budget and hey actually it's not so bad afterall. We very occasionally traveled by a real commercial plane, only if we really needed to, like when we migrated over to Thailand from Singapore because we brought along our dog and luggages were aplenty. But we took budget airlines only for short distance flight, e.g.: Malaysia-Indonesia, Singapore-Indonesia, Thailand-Indonesia, and everything else in between.

Flying intercontinentally to Europe would be challenging if we went by budget airlines, that's why we didn't mind splurging a little bit more on Turkish Airlines. Why Turkish Airlines? Simply because they offered the cheapest rate and the stopover was at Istanbul, one of the loveliest places we'd love to visit. To be honest, first choice was Emirates because we'd been dying to see what Dubai is like, and of course because we've been hearing the rave about Emirates. But again and again, it's budget that all mattered at that time.

Review of Turkish Airlines:
Bangkok - Istanbul (10 hours) - by A330 - 300
It's one of their new aircrafts (from what I read). Twice of meals were served and I must say they really put effort into that, at least their brochure looked really nice and professional. We're distributed a brochure of menu that let you choose which maincourse you'd like to have, which was coupled with an appetizer and dessert of course. A serving of tea and coffee also followed after meal. Entertainment inside the plane was highly up-to-date. I got to continue watching my How I Met Your Mother and Big Bang Theory series :) The only downside though, was room for the feet being a little bit too small, even for an Asian girl like me. To be honest I couldn't really catch a sleep because of this, but that's okay the entertainment made up for it.

Istanbul - Rome (3-4 hours) - by Boeing 737-800
Slightly smaller and without entertainment system. It's okay. Food was still amazing.

Paris - Istanbul (3-4 hours) - by A330-300
Same as Bangkok - Istanbul

Istanbul - Bangkok (10 hours) - by A340-300
Everything is the same as A330-300, only that the room for the feet was slightly more spacious. Nevertheless I still couldn't catch a sleep because people kept on mis-pressing the remote control on the side of their seats, which was pretty funny actually. :)
