this made my day

From Delta’s website:

Checked Baggage

You can check two bags per passenger free of charge.

Each bag must:

• Weigh 50 pounds (22.5 kg) or less.
• Not exceed 62 inches when you total length plus width plus height.

Exceptions:

• Passengers traveling to or from Key West and Marathon, Florida are limited to only one checked bag.
• The free weight allowance is 70 pounds (32 kg) for tickets purchased in Brazil, or for tickets purchased in Japan when traveling to/from Brazil.

For once, the fine print is working in my favor.
