The Ecommerce Merchant’s Guide to UPS 2nd Day Air

Last updated on February 24, 2025

UPS offers a host of services to ensure that your packages are delivered quickly to customers. Small improvements in which service you pick can have a big impact on customer experience and profitability, so in this guide we’ll walk you through your options and how to make the right choice for your business.
What is UPS 2nd Day Air?
As customer expectations for fast shipping increase, services like UPS 2nd Day Air gain prominence. UPS 2nd Day Air is an alternative for businesses that require fast, but not overnight delivery. It’s simple – slow delivery speeds blunt online store growth because products with slow shipping are added to carts less frequently, and their carts are abandoned more often than products that ship quickly. A 2023 Hanover Research study found that 86% of online shoppers see 2- to 3-day delivery as the baseline, and 63% say they would switch retailers if they could not receive their items within this timeframe.
UPS 2nd Day Air is one of a few expedited shipping options from UPS, and they describe it as their “economical option for shipments that do not need overnight service”. Designed to meet domestic shipping needs across the continental United States and Puerto Rico, 2nd Day Air ensures that a package will arrive at its destination in two business days but the ‘type’ of 2nd Day Air you choose will affect the delivery time.

UPS 2nd Day Air provides day definite delivery; ensuring packages arrive within a specified timeframe. But there are two different types of 2nd Day service – standard service and AM. When someone absolutely needs an item first thing in the morning, you need to spring for the much more expensive 2nd Day Air AM. Without 2nd Day Air AM, UPS only guarantees an end-of-day delivery time, which can of course stretch late into the night.
In addition to 2nd Day Air, UPS also offers 1-day and 3-day expedited services. The 1-day service is called UPS Next Day Air, and as you can imagine the 3-day service is called UPS 3 Day Select.
Benefits of Using UPS 2nd Day Air
UPS 2nd Day Air is a popular shipping option for businesses that need to deliver products quickly and efficiently. Here are some benefits of using UPS 2nd Day Air:
- Fast Delivery: UPS 2nd Day Air guarantees delivery by the end of the second business day, making it an ideal option for businesses that need to deliver products quickly. This ensures that your customers receive their orders promptly, enhancing customer satisfaction and loyalty.
- Cost-Effective: Compared to overnight shipping, UPS 2nd Day Air is a more cost-effective option. It allows businesses to save on shipping costs while still providing expedited delivery. This balance between speed and cost can be crucial for maintaining profitability in a competitive market.
- Reliable: With UPS 2nd Day Air, you get the peace of mind that comes with guaranteed delivery. UPS guarantees delivery within two business days, ensuring that your packages arrive on time and reducing the risk of delays that could impact your business operations.

This flexibility allows businesses to cater to various customer preferences and special delivery instructions, enhancing the overall shopping experience.
UPS 2nd Day Air Delivery Times
UPS 2nd Day Air delivery times vary depending on the destination and the time of day the package is shipped. Here are some general guidelines for UPS 2nd Day Air delivery times:
- Business Days: UPS 2nd Day Air delivery times are based on business days, which are Monday through Friday and do not count the date of shipment. This means that packages shipped on a Friday will typically be delivered by the end of the day on the following Tuesday.
- Delivery Begins: Delivery begins at 10:00 am, and the first packages are typically received by 10:30 am. This early start ensures that businesses can receive their shipments promptly and begin processing them without delay.
- Afternoon Delivery: For those who prefer later delivery times, UPS 2nd Day Air offers afternoon delivery, with packages typically arriving by 4:30 pm. This option is ideal for businesses that operate later in the day or for customers who are not available in the morning.
- Residential Delivery: UPS 2nd Day Air also caters to residential delivery needs, with packages typically arriving by 7:00 pm. This ensures that customers who are not home during the day can still receive their packages in the evening.
Overall, UPS 2nd Day Air is a reliable and cost-effective shipping option that offers fast delivery times and flexible shipping options. Whether you need to meet tight deadlines or provide convenient delivery times for your customers, UPS 2nd Day Air has the solutions to meet your needs.
How Much Does Shipping UPS 2nd Day Air Cost?
Cahoot’s internal shipping metrics show that UPS 2nd Day doesn’t come cheap – in fact, we observe that it’s often roughly two times as expensive as UPS Ground.
If you’re used to paying $8 or $9 to ship your packages via Ground and seeing them take a week to deliver, 2-day delivery is going to cost you somewhere in the upper $10 dollar range. In the hyper-competitive ecommerce world, an extra $5-10 in shipping costs can often be the difference between making and losing money on an order.
UPS 2nd Day Air AM balloons the cost of shipping far beyond the standard version of 2-day. Our data shows that the AM option nearly doubles the cost of standard – so it often comes in at nearly 4 times more expensive than UPS Ground. To us, the small added benefit of an early delivery won’t often justify the large added cost.
How to Ship Fast Without UPS 2nd Day Air
To quickly recap – customers expect fast shipping, so you need to offer it to boost growth. However, fast shipping is prohibitively expensive. If you’re like the vast majority of ecommerce merchants and can’t eat $10 extra in shipping on every single item, you need a better way.
The solution to this riddle is to ensure that you always have inventory close to the customer so that UPS Ground delivers in 1- to 2-days without the extra cost of 2nd Day Air – many call this a “distributed fulfillment strategy”. Typically, this means ensuring that you never ship farther than Zone 4, and it requires ~4 fulfillment locations strategically placed throughout the United States. This simple principle, though, is anything but simple in execution.

Here’s the three ways that merchants can adopt a distributed fulfillment strategy:
- Open Multiple Fulfillment Centers: merchants can open multiple US fulfillment centers and manage the four walls themselves. While having control may seem appealing, there’s never been a worse time to try to stand up merchant-operated fulfillment. Warehouse rents are hitting record highs, and if you can even find people to work for you, you’ll have to pay them $29.00 per hour to compete with Amazon’s rates. This strategy is also time-consuming and risky – you’ll spend countless managerial hours on operations instead of selling, and you’ll have to tie up significant capital.
- Marketplace Fulfillment Services: Amazon and Walmart offer their own in-house fulfillment networks; Amazon FBA and Walmart Fulfillment Services, for sellers on their platform. They enable fast shipping nationwide, and crucially, they allow vendors to place Prime Badges and Walmart TwoDay tags on their listings to boost visibility and conversion. While attractive, these solutions come with significant drawbacks. They’re designed for small products, so FBA is much more expensive for large items, while Walmart doesn’t accept them at all. Additionally, they’ll only solve your fulfillment needs for the marketplace itself. Amazon FBA’s multi-channel solution, Amazon MCF, is significantly more expensive than FBA, while WFS only works for Walmart orders.
- Third-Party Logistics Companies (3PLs): Your last option is to outsource fulfillment to one 3PL with national fulfillment services, or to multiple single-location 3PLs. The best 3PLs will have 10 or more locations across the United States, so they can strategically place your inventory right near your customer base. Modern 3PLs designed for ecommerce also have built native integrations with all major marketplaces and shopping carts, so you can use one provider for all of your fulfillment needs. Fulfillment costs will vary between 3PLs, though, and not all of them can meet the strict SLAs needed to win the Buy Box on every marketplace. Be sure to use something like a 3PL request for proposal (RFP) template to get an apples to apples comparison.
