A Few Limited Time Transfer Bonuses

Below are three different transfer bonus opportunities, two of which expire at the end of the day Saturday, and another that lasts through mid May.

Extended to End of October: Up to 62.5% Transfer Bonus from SPG to AAdvantage

Update 10/22/17: This transfer bonus was supposed to end October 15 but has been extended through October 31, 2017.

Until October 15, 2017, you can get up to a 62.5% bonus when transferring your SPG points to American Airlines AAdvantage. Previous SPG to AAdvantage transfer bonuses have offered a maximum of a 20% bonus.

30% Transfer Bonus: Membership Rewards to Virgin Atlantic

Transfers of American Express Membership Rewards to Virgin Atlantic miles will have a 30% bonus through November 30, 2017.

This is a fantastic deal that sets up a chance to book one way awards to Europe for 8,000 Membership Rewards+ $150.

You must transfer Membership Rewards in 1,000 point increments, so until November 30:

1,000 Membership Rewards = 1,300 Virgin Atlantic miles

LAST DAY: 40% Avios Transfer Bonus Means 24k Membership Rewards to Madrid in Business Class

Tomorrow is the last day to transfer Membership Rewards to British Airways and Iberia Avios with a 40% transfer bonus. The cutoff is 11:59 p.m. MT on September 17.

At the beginning of July we saw the transfer rate between American Express Membership Rewards and British Airways and Iberia Avios improve from 250:200 to 250:250

In a surprising and awesome turn of events, right after the new transfer rate was announced, a transfer bonus was also announced.

Largest Hotel Point to Aeroplan Transfer Bonus Ever Ends Tomorrow

Aeroplan's 30% bonus for transferring hotel points ends tomorrow night. If you have a stash of SPG or Marriott points, read this post to see if taking advantage of the bonus makes sense for your travel plans.

Through August 21 (11:59 ET), 2017, Aeroplan is offering the biggest bonus on record at the moment for transferring hotel points to Aeroplan miles. It's also not a tiered bonus like the others in the past have been. Transferring any amount will earn the advertised 35% bonus.

10% Transfer Bonus from ThankYou Points to Etihad

Citi is offering a 10% transfer bonus from Citi ThankYou Points to Eithad Guest through July 5, 2017.

If you have ThankYou Points earned by a Citi Prestige, Citi ThankYou Premier, or Citi Chairman card, then you can transfer ThankYou points to Citi's airline partners and are therefore eligible for the transfer bonus.
Using Etihad Miles for Etihad Flights
Etihad Guest Miles aren’t very good for booking First Class on the Etihad A380.

For instance, Etihad would charge 88,048 Etihad miles + $183 to book Abu Dhabi to London in First Class on the Etihad A380. 

During the transfer

Membership Rewards to JetBlue 25% Transfer Bonus Means 1:1 Rate

Transfers of Membership Rewards to JetBlue TrueBlue points will have a 25% bonus through 11:59 pm MT, May 31, 2017.

This could be a good deal if you have an immediate use for TrueBlue points. In other words, if there’s a cheap JetBlue flight you want to book and you have ThankYou Points, pay attention.

30% Transfer Bonus: Membership Rewards to Virgin Atlantic

Transfers of American Express Membership Rewards to Virgin Atlantic miles will have a 30% bonus through May 22, 2017.

This is a fantastic deal that sets up a chance to book one way awards to Europe for 8,000 Membership Rewards+ $150.

You must transfer Membership Rewards in 1,000 point increments, so until May 22:

1,000 Membership Rewards = 1,300 Virgin Atlantic miles

Hotel Points to Etihad Guest 20% Transfer Bonus

Through April 30, 2017, transfers from hotel partners to Etihad Guest will earn a 20% bonus.

Your best transfer options are probably between Starwood Preferred Guest and Etihad, or purchasing a Marriott Hotel + Air Travel Package that contains Etihad miles.

Normally, 20,000 SPG points = 25,000 Etihad miles (thanks to the everyday 5k bonus you get on transferring in increments of 20k), so with the current transfer bonus, 20,000 SPG points = 30,000 Etihad miles.
As One Mile at a Time pointed out, normally for Marriott Hotel + Air Package 2, you'd pay 270,000
