October 2026 transfer bonuses: Chase's record 70% to Marriott ends October 15 as three airline offers open

Amex, Chase, Citi, and Capital One have 7 transfer bonuses open in October 2026. Four carried over from September. Three opened on October 1: Amex to Air France-KLM Flying Blue at 25%, Amex to Aeromexico at 20%, and Capital One to British Airways at 20%.

Amex to Hilton ends October 14 and Chase to Marriott ends October 15. Citi's two offers, 30% to Japan Airlines and 25% to Avianca LifeMiles, run to October 24. The 3 new airline offers run to the end of the month. Aeromexico closes first, on October 30; some listings print October 31, so finish that transfer by the 30th.

Programs outside those four card issuers ran offers too. Rove pays 50% to Japan Airlines and 40% to Flying Blue through October 31, plus up to 35% to Qatar Airways for transfers of 100,000 miles or more. Bilt's October 1 Rent Day paid up to 200% to Hilton and up to 125% to Amtrak, capped at 100,000 points. Marriott Bonvoy adds 15% on transfers to Aeroplan through October 31.

Chase pays 70% extra on Ultimate Rewards moved to Marriott Bonvoy through October 15 at 11:59 p.m. Eastern. At 1:1, 10,000 Chase points become 17,000 Bonvoy points. Marriott posts the bonus up to 7 days after the transfer.

This is Chase's 16th Marriott bonus since July 2021. Eight of the 15 earlier offers paid 50%, and only 2 reached 70%: August 2024 and November 2025. The last one before September ran in two steps in 2026, 65% from May 1 to 15 and then 55% through June 30.

Amex to Aeromexico is the smallest airline bonus this month at 20%, but Amex's standard ratio is 1:1.6, so 1,000 Membership Rewards points become 1,920 Aeromexico points. Amex to Hilton starts at 1:2 and pays 2,600 Hilton points per 1,000 with its 30% bonus.

The 1:1 airline offers land closer together. Citi to Japan Airlines gives 1,300 miles per 1,000 points from Strata Premier, Strata Elite, and Prestige cards; no-fee Citi cards transfer at 1:0.7, or 910 miles with the bonus. Amex to Flying Blue and Citi to LifeMiles both give 1,250, and Capital One to British Airways gives 1,200 Avios. Rove's 50% to JAL beats Citi at 1,500 miles per 1,000.

Flying Blue prices business class between the US and Europe from 60,000 miles one way on its new Light fares, which carry no changes, refunds, or lounge access. That is 48,000 Amex points during the offer. Avios move between British Airways and Qatar Airways, where Qsuite awards from the US to Doha start at 70,000 Avios off-peak, about 58,400 Capital One miles with the bonus.

Amex has run 14 earlier Flying Blue bonuses since 2018. Eleven paid 25%, 2 paid 20%, and 1 paid 30%, in July 2021. The current 25% matches the June 2026 offer, 4 months ago.

Capital One to British Airways at 20% is the 6th bonus on that pair since 2021. Four of the 5 earlier offers paid 20%, the last in November 2025, and the high was 33% in August 2021. Amex to Aeromexico is the 7th since 2018. The first 3 paid 25%, the last in September 2021, and the 3 since then paid 20%.

Amex to Hilton is the 19th bonus on that pair since 2017; the largest was 50% in March 2020, and the last two, in April and July 2026, paid 20%. Citi's LifeMiles bonuses since 2018 have never topped 25%. Citi to Japan Airlines is the first bonus on that pair, launched when the route opened on September 20.

Transfers to airline and hotel programs are one-way. Find the exact flight or room in the partner program first, then move only the points that booking needs. Japan Airlines Mileage Bank also limits award tickets to the member and family.
