Amex Plat MR Boost to 100k and Sapphire Update

Amex Platinum Boost


Thanks to Ndel over at Flyertalk.com who successfully boosted the 50k Membership Rewards he signed up for back in March 2011 to 100k MR.
Persistence is key with this boost. If you are considering signing up for the 50k promo call their MR direct line and mention the 100k offer. If you already signed up for the 50k you can call or send Amex a secure direct message. If you are denied do not panic, continue to contact Amex about the promo and stay polite.Talking to the CSR with kindness is your best strategy for completing a successful boost. Make them want to give you the extra 50k. YMMV.

Update on Chase Sapphire Boost

Recent feedback from this offer shows approvals are slowing. Keep updated on the status of this offer here.
As awareness of this boost by applicants has grown it has for Chase CSR as well. They seem to be cracking down on the sudden increase in requests for the boost by stating it is for targeted customers only and you need a unique 12 digit identifier to qualify. 

As with most boosts, they are time sensitive. The longer you wait the more risk you take of being approved. I hope some of you got in on this deal and who knows, this offer may still have some legs on it yet.  YMMV.

Chase Sapphire Preferred Card Boost: 50k->100k points

UPDATE: Boost to 100k Points has shown signs of slowing down. Chase is now requesting your invite ID number. This post will be updated as the status of this offer continues to develop.


After the 100k BA Chase promo that expired this past May, Chase has another big bonus coming worth 50k points and a potential boost up to 100k! You can try to call in about the extra 50k before even registering or if you already have been approved for the card I suggest sending a secure direct message.  
If you applied for Chase credit card in past 30 days you are unlikely to be approved. YMMV.


Abstract:

• 50,000 points can be worth up to $625 in flights.
• 1:1 Transfer to British Airways, Continental, Hyatt, Marriott or Priority Club.
• No Foreign Transaction Fee 
• Annual Fee is waived for first year.
• Requirement: Spend $3,000 in 3 months.
