I had a look at wt+ but couldn't get that price, although we did pay that this last summer.
I like Qatar economy but not good prices yet. Emirates- didn't look at them.
I have only flown Lufthansa twice and that was years ago. KLM- been a long time as well. At that time there was no contest- BA was best. Now I am not so sure.
Finnish had a great price but I am not spending 31 hours getting to Bangkok! Thanks Henkybaby
