I usually fly AA SFO-PHX every other Sat night but this flight is gone for Jan, and Feb. Am thinking about flying Frontier for those months. I travel with a Rollaboard and a school type backpack. If I status match to 100K will I need to worry about these two carry ons? Anyone fly this route regularly? Seems like 1 out of 10 flights gets delayed. Does not look like there are any other Frontier options after that flight so any delay is just a wait it out scenario.
