Your best bet is to visit a travel agent as they should be giving you the best advise. Do remember that ticket prices depends on the season and each country has it own high peak season and low peak season. So while someone may say a certain airline was best in terms of cost and allowance , it would have been for that period of their travel and may not necessarily be true for when you want to travel. The only true responses you could gauge here would be related to flight experiences with airlines and on-board services and amenities etc. In that respect there are certain airlines ( EK , SQ ) who are well beyond the rest.
