The USPS expects to deliver more than 8 million packages each Sunday in December, the agency said.
CNN  — 

Don’t panic, you still have some time to get your presents delivered before Christmas next week.

But don’t dilly-dally – this week is the busiest of the holiday mailing and shipping season in the United States, with the US Postal Service expecting to process and deliver nearly 3 billion pieces of mail, the USPS said in a news release.

The USPS says in the period from December 10 to December 23, it expects it will have delivered nearly 200 million packages.

From Thanksgiving through New Year’s Day, the postal service predicts it will make a total of nearly 16 billion mail and package deliveries. The agency has expanded its Sunday operations to help with the surge in holiday deliveries.

The numbers are scary, considering these are the statistics from one single mailing agency, but you still have a chance to have your package delivered before Christmas.

Today is the deadline for UPS’s most affordable delivery option, the UPS 3 Day Select, as well as the deadline for free shipping on Amazon orders. Tomorrow, December 19, is the deadline for FedEx’s “Express Saver,” and December 20 is the deadline for USPS’ first-class and priority mail.

To make sure your present arrives on time, these major US carriers suggest you ship your package on or before the following dates:

Traveling with presents

If you’re traveling by plane for the holidays, here are some tips from the Transportation Security Administration to keep in mind:

  • If you’re bringing gifts with you, do not wrap them. The TSA suggests to bring your presents unwrapped, in a bag, or in an easy-to-get-to box, in case officers need to open them for a safety check.
  • The TSA wants you to know that if you spent all night baking those Christmas cookies, it’s perfectly ok to pack them in your carry on, but if it’s eggnog or any other liquid, it must be 3.4 ounces or less.
  • If you’re not sure if your present is safe enough to carry through the checkpoint, the TSA suggests you visit its “What can I bring?” section on its web page.
  • Remember, many people travel for the holidays, which is why the TSA suggests getting to the airport earlier than usual, and “use your time at the checkpoint wisely.”
  • Finally, if you think you left something behind at the checkpoint, don’t panic – the TSA has a lost and found program that will help you find your missing items.
