British Airways has bumped its Avios Balance Boost multiplier up to 5x, from the usual 3x cap, through September 16. If you've earned Avios in the last 30 days, you can multiply them for cash at a genuinely good rate.

• Bonus: buy up to 5x the Avios you earned in the last 30 days (normally capped at 3x)

• Effective rate: about 0.92p per Avios (roughly 1.24 US cents)

• Cap: 300,000 Avios per calendar year via Boost

• Expires: September 16, 2026, 11:59pm BST

• Sweet spot: boost a recent card-transfer batch to round out a Club World redemption

Air Canada's Aeroplan program just launched a fresh buy-points sale, running September 11-25. If you've got a redemption in mind, this is one of the better buy-points deals we've seen this month.

• Bonus: up to 100% (some targeted members are seeing up to 110%)

• Effective rate: 1.35 cents per point (USD) at the 100% tier

• Cap: 500,000 points per transaction, 1,000,000 per calendar year (pre-bonus)

• Expires: September 25, 2026

• Sweet spot: a one-way business class seat to Europe (around 60,000-70,000 points) for a fraction of the cash fare

Got a trip already on the calendar? This is worth running the numbers on. If you buy in, let us know what you're booking with them.

If you're a few thousand Virgin Points short of an Upper Class redemption, this is worth a look - Flying Club just opened its buy-points window with a 70% bonus at the top tier, and UK accounts get the better end of the pricing on this one.

• Bonus: tiered up to 70% (20% at 5k-39k points, up to 70% at 125k-400k points)

• Pricing: £15 per 1,000 points plus a £15 fee for UK accounts (cheaper than the US $25/$22 pricing)

• Runs through: October 4, 2026

• Best use: topping off for Upper Class to India or the Caribbean - not a currency to buy in bulk

Anyone topping off for a specific Upper Class trip with this? Curious what route people are chasing.
