For anyone looking to get the Chase United Explorer card, you may be able to get a 50,000 point bonus
+ 10,000 after $25,000 in spend by signing-in to your United account. I was able to see the offer and I am not elite on United or Continental. Daraius over at MillionMileSecrets
has also confirmed it as well.You can get 1,500 bonus AA miles
when renting from Avis for 3 or more days.
You can still get up to 105,000 bonus miles from AA for flying round-trip to Europe. Please note the required fare buckets.
TripAlertz is still giving away $5 for every person you invite. You can use my link if you need to join or one of the links in the comments.
