I am trying to book 4 business class tickets from HYD-DFW, during summer this year. Only option (for the dates I prefer around July 4th weekend) is flexi tickets with mixed class cabin

HYD-DOVH - economy
DOH-DFW-Q Suite

each for 175,000 avios, total 700k avios + $1000 almost in taxes/fees

Is this cost worth it? Any better suggestions if I want to fly business class?

Also, any chances of getting business upgrade for the first leg from HYD-DOH I go forward with this one?
