redeemed one just last week. akl bkk I award (business) connecting onto bkk lhr O award (first) on TG.

if it vital you have EF to hunt down the availability on these. I managed to find more than enough availability. good thing about bkk lhr in first is the new format 747 all series with 9 suits. all in cost as follows.

akl bkk 1750apd business class award I class
bkk lhr 1550 first award O class
100 apd fee (payable cash or apd)
Tax $ 65.

I paid 65 tax as I am doing a 16 lay over in bkk (Arrive 20.50 depart 12.50 + a day) in order to enjoy two day flights and get more use out of the TG first lounge and spa in Bkk. yiu can connect to a flight to lhr within 3 hours and that way you would pay $35 in taxes.any other questions please ask.

justed noted you wanted to do reversal route from europe. what about OZ in O fra via ICN. they usually have availability in that direction
