I'm going to be booking a round trip first class seat on United. Based out of EWR, so 99% of the time, I fly United and JetBlue.

I can easily spend $1,000-$2,000 in first 3 months (ticket for this trip will be about $700)

I currently have:
Citi DoubleCash
Chase Disney Visa

I'm really hoping to earn miles that can be used toward a future trip and really want to get the most value out of booking this first class seat. FICO credit score is excellent (800+), so no concern there.

With the new month starting, anyone have recommendations as to what to get? Not sure if a $450/yr card can be justified, but $95 I suppose is doable depending on the value the card gives.

Thanks in advance!
