The Hawaiian Airlines Visa Signature card is offering 35,000 miles after you spend $1000 within 4 months and you also get a companion ticket for 50% off.
FYI, 40,000 miles is equal to 1 round trip ticket from Los Angeles to Hawaii.
I am thinking about converting the 35,000 Hawaiian miles to Hilton points, which gives you 3x the 35,000 miles. this equals 105,000 Hilton points.
