Hi,

I need some advice. After a lot of traveling for work I'm finally using some miles to fly down on a 2 week vacation to Australia.

Since I wanted to get the experience of flying First I was able to find a good itinerary with the SaverPass First option. For different reasons I only booked a R/T to Sydney and most of the travel is on Thai Airways (even doing a quick stop in BKK for a few days!), which flies out of LAX-BKK-SYD.

Currently my return is SYD-BKK on First class and then BKK-LAX on Business (No First class cabin)... My return flights have the same class of service.

I was trying to extend my stay in Australia and even fly back from Melbourne, right now I found an option that would get me a few extra days but it's flying back on UA's 840/870 flights (via SFO).

Here's my question. Will I regret flying UA's First all the way back after doing Thai Airways First/Biz? (Which at least I can say I experienced since I did it on the way in?)

Thanks for any advice!
