I have vacation that week so I do not have to urgently come home on any schedule.
If I get stuck overnight in LAX or LAS oh well.
If a flight or two doesn't pan out, then I will strive for having original routing credit (including credit for a roundtrip) or a refund.
I won't have kids in tow, or bags. I basically want to bang out 3 roundtrips for $500 and play some cards. If it works out fine, if not fine.
I'd rather try to bang them out quick then wait 4 hours per leg in the airport to be safe.
It's different than having a condo in Aruba booked for a week, and not having a backup flight available for 4 days and having 6 tix paid for and connecting in ATL during SNOWMAGGEDON
