Lesson learned. Will do the match before booking next time. I booked via Hilton website, and submitted two BPG claims within 24 hours:
The Traveluro one got denied the second day, same reason as mentioned in this thread, "Reservations booked via traveluro.com are not instantly confirmed. Once you make the reservation you have to wait 30 minutes to receive a confirmation email, and you will receive the hotel confirmation number 24 hours prior to the arrival date, whereas reservations booked via our website are confirmed immediately with a hotel confirmation number. "
The Algotels claim has not been responded, it has been 3 days, but the price has gone up. Can't get it matched now.
