Lots of flights from USD1k -1.4K on Ettihad , Emirates, Qatar etc Stay away from US carriers and you will be fine. There are lots of search engines, try them?
As long as you have a visa and dress nicely and wear shoes and not flip flops and shorts you should be okay. If you look okay and are polite there is no real reason to deny you entry.
Who knows, depends on the officer at the time . If you are decently dressed and polite I see no proble. If you are in shorts flip flops and a tee shirt it may be different?
I had a US friend and he couldn't get any pension cheques debitted to a Thai Bank I hadd to go to an ATM using his credit Union card to get funds for him many times.
