All missions are cleared for takeoff no later than the 15th of every month.

• Domestic Crew: Expect arrival within 3–8 business days.

• International Crew: Custom flight plans are handled via email; please contact penpalpilot@pm.me

Simply transmit an email to penpalpilots@pm.me and our ground crew will update your flight plan or end your subscription immediately. To ensure your next letter reaches the correct coordinates, please submit all changes before the 1st of the month.

If you sign up before the 1st, you will recieve the previous month’s letter. If you sign up after the 1st, your first letter will arrive the following month (e.g., sign up before March 1 to recieve February’s letter).

If your envelope doesn't arrive, email us and we will initiate a search and rescue. We will either re-deploy a fresh dispatch or provide a full refund for the month. We monitor USPS closely, but if a letter bounces back to our HQ, we will hold it until the end of the month and re-attempt delivery once we verify your coordinates

We currently only ship letters domestically to coordinates serviceable by a standard USPS stamp. For international aviators interested in signing up, please send an email to penpalpilot@pm.me to discuss custom delivery options.
