One of the best flight deals is back again! Sign up for a British Airways Visa Card to get 50,000 bonus Avios (the name for British Airways miles) when you spend $1,000 in 3 months, which can be enough for a round-trip economy ticket to Europe. After signing up and spending $1,000, you'll have 51,250 miles after the bonuses and the standard 1.25 miles per dollar spent. Then, for example, redeem 40k miles for an economy class flight from the East Coast to Europe. There's a $95 annual fee. BA adds high surcharges to their flights, but you can use their miles on partners like American Airlines or Cathay Pacific. Review this British Airways Card analysis with extras like how you can earn a free companion business class ticket for your spouse. This isn't just for Europe. You can book flights on American with BA miles (for less than what American requires!) See the 3 Best Ways to use your 100,000 miles or why 100,000 BA Miles is more like 200,000 American Miles. I often use 4,500 to book one-way domestic flights that would cost $250 or more, which means 50,000 BA miles are worth more than $2,500 to me!
