In order to get holiday gifts to deployed service members by Dec. 25, mailers should heed the U.S. Postal Service’s suggested deadlines. Parcel post packages to deployed troops and those living on overseas installations should be sent by Nov. 13. Customers missing the parcel post deadline have the following options: Space-Available Mail (SAM) — Nov. 27; Parcel Airlift Mail (PAL) — Dec. 4 (except for ZIP codes starting with 093, which is Dec. 1); Priority Mail and first-class letters and cards — Dec. 11 (093 ZIP codes: Dec. 4); Express Mail Military Services — Dec. 18 (not available to 093 ZIP codes). Parcel post packages sent to arrive by the start of Hanukkah at sundown Dec. 4 should be mailed by Oct. 23. For other Hanukkah mailings, subtract 21 days from the deadlines listed above.
