Bask Bank: 20,000 AAdvantage Miles for a New Savings Account (Catch: $50,000)

Bask Bank is offering 20,000 American Airlines AAdvantage miles when you open your first Bask Mileage Savings Account and hold the required balance. It is a legit way to earn a chunk of AA miles without a credit card, but the deposit is steep, so it really only makes sense if you have a large amount of cash sitting idle.

• The bonus: 20,000 AAdvantage miles for new Bask Mileage Savings customers (you cannot have had one before).
• The catch, and it's big: maintain a $50,000 minimum daily balance for 90 of the first 120 days. Fund within 15 business days of opening.
• The real cost: this account pays miles instead of interest, so while your $50,000 sits here it is not earning the cash interest a high-yield savings account would. That forgone interest is the true price of the miles. Only worth it if that cash would otherwise sit idle.
• Open by: November 30, 2026. Miles post about 10 business days after you meet the terms, then take 6 to 8 weeks to reach your AAdvantage account.

Bottom line: 20,000 AA miles is real value, but this is a cash-parking play. If you can lock up $50,000 for four months, it is nearly free miles. If you would give up meaningful savings interest, do the math first.
