Welcome to FT csharma137.RTW ex-DEL has a 12.5% surcharge so the one ex BKK is better. In that case you may want to consider a o/w LAX-BKK in Premium Economy for $1042 o/w and then start your RTW from BKK ( a 29,000 in J is 5700 CDN bookable with AC but at least one leg--Trans atlantic or transpacific-- must be on AC). You get full AC points and I understand the TG forum will be able to give you ideas about the premium Economy on the TG non stop from LAX-BKK. Hope this helps.
