Just a note about flying THAI F BKK-CDG.

THAI offers F in 747 and 346 aircraft. The 346 has a modern interior and flies mainly to ZRH (in europe), so you'd need a connection to CDG.

There are 2 configurations of 747 - one with 'old' F and C seats (6 aircraft, code 747) and another with refurbished F and C seats (12 aircraft, code 744) with config similar to the 346.

THAI occasionally swaps a newer config for an older config, which usually results in disappointment for those who were expecting the modern interior. LHR/FRA seem to experience such changes only rarely, but I recall that CDG has a higher swap rate.

Others here who fly to EU can provide their experiences, especially the 'odds' or frequency of such 'configuration downgrades'.

I did a date by date check, and the ANA tool shows availability up to, and including 30 Oct. I suggested that have patience and try regularly (daily, weekly - up to you).

Cheers, TK
