Yes, you can combine miles in 2026, but the method and "cost" depend on the airline. Many major 2026 programs now offer "Points Pooling" or "Family Sharing" for free. For example, Air Canada Aeroplan allows up to 8 family members to pool their points in a single "Family Sharing" account. United Airlines recently introduced "Miles Pooling" in 2024, allowing groups of five to share miles for free. Similarly, British Airways (Household Accounts) and JetBlue (Points Pooling) allow spouses to consolidate their balances. However, if you are flying with an airline that doesn't offer pooling (like Delta or American in some regions), you would have to "Transfer" miles from one account to another, which usually incurs a steep fee of roughly 1 cent per mile plus a processing fee. In 2026, the "smart" strategy is to join a "Family Pool" at the start of your journey to ensure your collective miles are always ready for a single large redemption.
