For anyone asking what is UPS 2nd Day Air: it is the UPS air service that delivers a package in two business days. It sits between Next Day Air and 3 Day Select on the UPS ladder. UPS says it delivers to all 50 states and Puerto Rico, with some limitations in Alaska and Hawaii.
The service name says “day,” but UPS counts business days. Weekends and holidays usually do not count. This page covers timing, the guarantee, Saturday options and how it compares.
What is UPS 2nd Day Air and what does it mean?
The name is a delivery promise in the title. You hand UPS the package, and UPS plans for it to arrive two business days later. Shipping on Monday normally points to Wednesday.
Some people search for “what is UPS second day air.” That is the same service. UPS writes it as 2nd Day Air, and the number and the spelled out word mean the same thing.
It is an air service, so it costs more than Ground. It sits in the same family as Next Day Air. UPS accepts packages up to 150 pounds and 108 inches in length on this service.
How long UPS 2nd Day Air takes
How long does UPS 2nd Day Air take? Two business days from pickup or drop off. A Friday drop off lands on Tuesday unless you add Saturday delivery.
The UPS domestic services page does not list a delivery by time for plain 2nd Day Air, so plan on the end of the second business day. Residential and business addresses can get different times, so read the time shown on your quote before you pay. Do not assume a morning arrival unless the quote says so.
Does it include weekends?
Not by default. Saturday and Sunday are not business days for the count. UPS offers a Saturday option, but its domestic services page lists no Sunday option.
Is UPS 2nd Day Air guaranteed?
Plain 2nd Day Air is not guaranteed right now. UPS says its Service Guarantee covers only four domestic services. For all others it “remains suspended.”
Plain 2nd Day Air and 3 Day Select have no money back promise now, so a late package gets no automatic refund. Refund terms for guaranteed services sit in the UPS Tariff, with conditions and exclusions. You can read the current wording on the UPS Service Guarantee page.
What 2nd Day Air A.M. changes
The covered services are Next Day Air Early, Next Day Air and Next Day Air Saver, plus the one on this page called 2nd Day Air A.M.
That version is covered by the guarantee today. UPS lists it for the 48 contiguous states and limited addresses in Alaska and Hawaii, with Saturday delivery available, but it does not state the exact morning hour on its service page or its guarantee page, so confirm the commitment time in the UPS rate tool before you ship.
UPS 2nd Day Air vs 3 Day Select vs Next Day Air
These three services share the same weight and size limits, and UPS sells all of them as air or express options. The difference is speed, coverage and the guarantee. Use the table to see where 2nd Day Air fits.
| Service | Transit time | Coverage | Saturday delivery | Guaranteed now |
|---|---|---|---|---|
| Next Day Air | Next business day | All 50 states | Yes, for Early and standard | Yes |

Next Day Air is the faster pick, and our guide to what UPS Next Day Air is covers its three versions. 3 Day Select costs less and takes one day longer. 2nd Day Air is the middle choice when the deadline is close but not tomorrow.
What is UPS Blue?
“UPS Blue” is a nickname, not a service name UPS uses on its domestic services page or its guarantee page. People use it for the second day air service. Treat it as slang that points to 2nd Day Air.
The safest way to be sure is to look at the service name on your shipping label or tracking page. If it says 2nd Day Air, you have the service this guide describes.
Who uses UPS 2nd Day Air
Shippers pick UPS 2nd Day Air for speed that stops short of overnight. Most of them have a firm date and some room to spare.
Businesses use it when a customer needs an item soon but not overnight. It is common for replacement parts, medical supplies, documents and online orders where the buyer paid for faster shipping.
Individuals use it for the same reason: a deadline that is two days away. A gift, a form or a forgotten item fits well. Compare quotes for Next Day Air and 2nd Day Air to see the real gap.
- Choose 2nd Day Air when the item must arrive within two business days.
- Choose Next Day Air when the delivery cannot slip a single day.
- Choose 3 Day Select or Ground when the date is flexible and price matters more.
What UPS 2nd Day Air costs
UPS does not publish one flat price for this service. The price depends on weight, package size, the distance between the two ZIP codes and the address type. Dimensional weight can also raise the charge on a large, light box.
Use the UPS calculator for an exact quote, then compare the result in our shipping cost comparison tool.
To see whether two business days really reaches your date, try the delivery time estimator. Enter your ship date and both ZIP codes before you buy. Then compare the result with the Saturday option if the date is tight.
Before you ship
Knowing what is UPS 2nd Day Air only helps if the dates line up. Plan from the day UPS actually has the package. UPS does not publish a single national cutoff on its service page, because cutoffs depend on the location and the pickup schedule, so check the cutoff for your drop off point.
Count the business days from the pickup date and watch for holidays. A holiday can add a day to the count. Check whether UPS is open on Labor Day before you choose a ship date.
The same applies in October, covered in our page on whether UPS delivers on Columbus Day.
