How much stamps to the Philippines regular letter airmail?

As of my last knowledge update in October 2023, the cost of sending a regular letter by airmail to the Philippines typically depends on the weight of the letter and the postage rates set by your local postal service. In the United States, for instance, a standard first-class letter weighing up to one ounce costs around $1.40. It's best to check with your local postal service for the most current rates and any specific requirements for international mail.
