United Commits to a Cleaner Future - United Hub

We commit to a cleaner future by pledging to reduce our greenhouse gas emissions

By United Airlines, September 13, 2018

Today was a historical day — we became the first U.S. airline to publicly commit to reducing our greenhouse emissions — 50 percent by 2050. This pledge further strengthens our commitment to becoming the world's most environmentally conscious airline. Achieving this goal would eliminate 21 million metric tons of CO2 in the atmosphere per year, equivalent to removing 4.5 million cars off the road or all of the cars in Los Angeles and New York City combined.

In order to meet that goal, we're making investments in fuel-efficient aircraft, implementing conservation-minded operational changes and pioneering the use of sustainable aviation biofuels.

Our CEO, Oscar Munoz, applauded the move, stating that in addition to being good for the environment, reducing our dependency on oil is good for our business. "At United, we believe there is no point in setting challenging and ambitious goals without also taking tangible steps towards achieving them, especially when it comes to securing the health of our communities and our planet," said Oscar Munoz, United's chief executive officer. "While we're proud to be first U.S. carrier taking such an ambitious step, it is a distinction we look forward to sharing as the rest of the industry catches up and makes similar commitments to sustainability."

To celebrate this historic commitment, we are operating the longest transatlantic biofuel flight to date, tomorrow, from San Francisco to Zurich. The flight will run on 16,000 gallons of biofuel at a 30/70 blend with conventional jet fuel supplied by World Energy, California-based refinery that converts feedstocks into low-carbon biofuel that cuts CO2 emissions by 60 percent on a life-cycle basis. Since 2016, we have sourced more sustainable aviation biofuel than any other carrier in the world. Our partnership with World Energy started back in 2016, with our inaugural flight from LAX. We will continue working together to decarbonize the air transportation industry by increasing the number of flights using renewable fuel.

"This flight is one of many steps needed to reduce greenhouse gas emissions long-term and meet California's ambitious climate goals," said Bryan Sherbacow, Chief Commercial Officer, World Energy Paramount. "World Energy is a pioneer and the global leader of commercial renewable jet fuel, in addition to providing low-carbon solutions to the ground transportation industry. We are excited to continue to provide low-carbon solutions that enable our customers to achieve their sustainability goals and look forward to continuing this work with companies such as United at airports around the world."

Our efforts to be the greenest airline in the industry is about the future of our business and more importantly, our skies. For more information on how we're flying towards a more sustainable future, visit our Eco-Skies® page.

Critical medical shipments – Check.

High-tech electronics – Check.

2.7 million pounds of lobster? Check.


While this year's holiday gatherings will look a little different, millions of people around the world will still carry on the tradition of celebrating the holidays with a meal.

As the appetite for different types of food from all over the world increases, so does the need for safe and reliable transport. Fish caught in the United Kingdom can depart at breakfast and arrive in Washington D.C. in time for dinner. Thanks to United Cargo's expansive network, we are longer constrained by global distance or the seasonality of a product,

United Cargo plays a big role in transporting shipments with a limited shelf life around the world. Packed in between the latest electronics from Asia and the hottest fashion items from Europe, our aircraft carry a variety of perishable shipments like flowers, fruit, meat and vegetables, where speed and careful handling keeps them fresh. Whether it's cherries from Washington State or vegetables from Peru, our temperature-controlled shipping processes and vast global network helps move these commodities all over the world.

While the holidays are an exceptionally busy time of year for shipping perishable items, United Cargo transports these critical goods for people all over the world year-round. Earlier this year, United Cargo moved nearly 190,000 pounds of fresh produce to Guam for the U.S. Department of Agriculture's Coronavirus Farm Assistance Program to support communities impacted by COVID-19. Additionally, with the holiday season here, we anticipate the cargo holds of our aircraft to be full of grocery store replenishments, including staples like turkey and ham, hitting shelves across the globe.

We take pride in our role to make sure perishables and produce arrive on time and at the peak of freshness. These products sustain, feed and nurture the world, and consumers around the globe depend on them every single day.

Since March 19, United has operated nearly 8,000 cargo-only flights, moving over 272 million pounds of cargo on those flights alone. United Cargo is proud of the role we play maintaining the global food supply chain and helping people access commodities from all over the globe.

Bon appetit!

By The Hub team, November 19, 2020

Whether you haven't flown with us for a while or just need a quick refresher before your holiday travels, read this list of tips to know before your flight and arrive travel-ready:

1. Download the United app for contactless bag check, payments and more

Before your flight, download the United app to view your flight status, check in, sign up for flight notifications, locate departure gates, access our free personal device entertainment when available and more. We've also updated our app with new features that can make your trip a little safer, including contactless bag check and touch-free onboard payments.

2. Read and sign the Ready-to-Fly checklist

Before completing check-in, all United travelers will need to read our Ready-to-Fly checklist and confirm that they understand and agree to our policies. These include:

  • Acknowledging that you haven't had any symptoms of COVID-19 in the last 14 days
  • Agreeing that you will not fly if you have tested positive for COVID-19 within the last 21 days
  • Confirming that you will follow all policies regarding face coverings, social distancing and other health and safety measures we've adopted

3. Get familiar with CleanPlus

United CleanPlus℠ is our commitment to delivering industry-leading* cleanliness, plus putting health and safety at the forefront of your experience, in partnership with Clorox and Cleveland Clinic. We've implemented CleanPlus in a number of ways that you'll notice throughout your trip, as well as with some behind-the-scenes enhancements like:

  • Disinfecting high-touch areas on board and in the terminal
  • Using electrostatic spraying, Ultraviolet C lighting wands and more advanced measures to clean aircraft cabins before boarding
  • Redesigning our mobile app to allow for touchless check-in and contactless payment, along with enhanced travel assistance features

Studies show COVID-19 exposure risk is minimal when air filtration systems and masks are in use, so you can rest assured that the steps we've taken to keep you safe truly make a difference.

4. Don't forget essential documents

We've made a list of travel requirements and restrictions for every destination that you can check twice, or as often as you need before your trip. Just visit united.com/travelrequirements to get the details on COVID-19 testing, health documents and other things you may need before you fly.

5. Wear your mask

You may not notice our smile behind our face covering, but you can be sure that we're appreciative of all our travelers who arrive to the airport with their mask on, and continue to wear it over their nose and mouth at all times in the airport and on board. Make sure you review our requirements for face coverings, including what an acceptable face covering looks like. Bonus points if your mask infuses some holiday cheer!

6. A better boarding process for your safety

If you haven't flown with us in a while, you might want to get familiar with our new boarding process. To make boarding even safer, we now have travelers board their aircraft from back to front. At the gate, just listen for your row number to be called – we'll ask a few rows at a time to board, starting with the last row of the plane. This helps everyone maintain a safe distance from each other during boarding without slowing things down. As you step onto the plane, flight attendants will hand each passenger a sanitizing towelette, which you can use to wipe down your seat to ensure it's extra clean.

7. Pack smart

Before packing your bags, check to see what exactly you can carry on and what you should plan to check. You can also copy your confirmation number into our Baggage Calculator tool to learn about the bag allowance included with your reservation, as well as the cost of checking any additional bags.

8. Check your flight status, important notices and weather

Check the United app regularly for the latest updates, weather conditions, flight status, gate and seat assignments. You can also visit our Important Notices page to find essential information and updates about travel waivers, international travel, TSA and security, airports and United Club locations.

9. Arrive early; avoid the stress

Airports can be busy, especially during the holidays. The TSA advises arriving at the airport two hours before your flight for domestic travel and three hours for international travel in anticipation of long security lines. This can help ease the stress when navigating busy check-in areas, security lines and crowded boarding gates.

10. Relax and enjoy your flight

Once you're on board, it's time to sit back and enjoy your flight. Our flight attendants will be happy to help you with anything else you need.
