Had my first experience using the CSR "Points Boost" when I tried to book airfare for my upcoming trip to Bonaire.

The only itinerary where Points Boost was offered was an AA flight that had a 25 minute connection. First Class was just a few hundred dollars more than the Main Cabin with seat selection (maybe $1400 v 1100), but I didn't trust the 25 minute layover and chose to book with Delta.

Chase Travel offered the Delta flight with a 2 hr layover in ATL for ~$2000pp and 300,000 URs. I booked it directly with Delta for cash instead for ~$1200pp cash.

Rental car was similar. Avis mini-van was $708 or 47,186 URs on the Chase portal. Booked through Delta for $340, albeit the latter was a Suzuki v Dodge Caravan.
