Access Now v. Southwest Airlines was a case where the District Court decided that the website of Southwest Airlines was not in violation of the Americans with Disabilities Act, because the ADA is concerned with things with a physical existence and thus cannot be applied to cyberspace. Judge Patricia A. Seitz found that the "virtual ticket counter" of the website was a virtual construct, and hence not a "public place of accommodation." As such, "To expand the ADA to cover 'virtual' spaces would be to create new rights without well-defined standards."[76]
In 2010 the U.S. Department of Justice (DOJ) released the 2010 ADA Standards for Accessible Design. This update to the Americans with Disabilities Act of 1990 has consistently been interpreted by U.S. courts to apply to digital content including websites, applications, mobile apps, and PDFs. The Web Content Accessibility Guidelines (WCAG) are technical guidelines referenced when testing for ADA website accessibility. Today, WCAG 2.1 A & AA is considered the minimum standard for ADA website compliance.
Until the ADA is updated to address the special case of website accessibility, or the Department of Justice releases its website accessibility regulations, complying with WCAG 2.0 Level AA is the best way to ensure that people with disabilities have equal access to your website. The overview below is a great starting point about meeting the WCAG 2.0 Level AA recommendations.
There are several phases to go through to make a website ADA accessible. First, it is important to have your existing website evaluated for ADA accessibility. Have this evaluation done by a company that specializes in ADA compliance for lodging properties. Most existing websites will not pass a detailed ADA evaluation. Depending on the results of your professional ADA inspection, you will either have to make necessary changes to your existing website, or have it redesigned to meet ADA accessibility guidelines. 
HTML tags – specific instructions understood by a web browser or screen reader. One type of HTML tag, called an “alt” tag (short for “alternative text”), is used to provide brief text descriptions of images that screen readers can understand and speak. Another type of HTML tag, called a “longdesc” tag (short for “long description”), is used to provide long text descriptions that can be spoken by screen readers.
For most businesses, the need for ADA web compliance means they will need to make at least some adjustments to all of their online marketing strategies. For instance, if your company provides tax preparation services, all of the tax forms you provide for customers to download would need to meet accessibility standards. Any online tax preparation services that you offer would also need to be configured so they meet ADA standards, as would your mobile app.
Tennessee v. Lane[80], 541 U.S. 509 (2004), was a case in the Supreme Court of the United States involving Congress's enforcement powers under section 5 of the Fourteenth Amendment. George Lane was unable to walk after a 1997 car accident in which he was accused of driving on the wrong side of the road. A woman was killed in the crash, and Lane faced misdemeanor charges of reckless driving. The suit was brought about because he was denied access to appear in criminal court because the courthouse had no elevator, even though the court was willing to carry him up the stairs and then willing to move the hearing to the first floor. He refused, citing he wanted to be treated as any other citizen, and was subsequently charged with failure to appear, after appearing at a previous hearing where he dragged himself up the stairs.[81] The court ruled that Congress did have enough evidence that the disabled were being denied those fundamental rights that are protected by the Due Process clause of the Fourteenth Amendment and had the enforcement powers under section 5 of the Fourteenth Amendment. It further ruled that "reasonable accommodations" mandated by the ADA were not unduly burdensome and disproportionate to the harm.[82]

Title IV of the ADA amended the landmark Communications Act of 1934 primarily by adding section 47 U.S.C. § 225. This section requires that all telecommunications companies in the U.S. take steps to ensure functionally equivalent services for consumers with disabilities, notably those who are deaf or hard of hearing and those with speech impairments. When Title IV took effect in the early 1990s, it led to the installation of public teletypewriter (TTY) machines and other TDD (telecommunications devices for the deaf). Title IV also led to the creation, in all 50 states and the District of Columbia, of what was then called dual-party relay services and now are known as Telecommunications Relay Services (TRS), such as STS relay. Today, many TRS-mediated calls are made over the Internet by consumers who use broadband connections. Some are Video Relay Service (VRS) calls, while others are text calls. In either variation, communication assistants translate between the signed or typed words of a consumer and the spoken words of others. In 2006, according to the Federal Communications Commission (FCC), VRS calls averaged two million minutes a month.
Another important consideration is that the ADA does not allow businesses to simply provide an alternative such as a phone number. Lastly, include accessibility issues as part of your website and mobile strategy. When new technologies are implemented or pages added, part of the process should include the implications for persons with disabilities. 
Part of Title I was found unconstitutional by the United States Supreme Court as it pertains to states in the case of Board of Trustees of the University of Alabama v. Garrett as violating the sovereign immunity rights of the several states as specified by the Eleventh Amendment to the United States Constitution. The Court determined that state employees cannot sue their employer for violating ADA rules. State employees can, however, file complaints at the Department of Justice or the Equal Employment Opportunity Commission, who can sue on their behalf.[19]
Enough Time: Users have sufficient time to read and use the website’s content. If part of the website has a time limit, users are able to turn off the time limit, or they can adjust or extend it to at least ten times the default limit (unless the time limit is essential to the website’s functionality, such as auction websites like eBay). Content that moves, blinks, or automatically updates can be paused or stopped unless it’s essential to the website’s functionality.
The attorneys' fees provision of Title III does provide incentive for lawyers to specialize and engage in serial ADA litigation, but a disabled plaintiff does not obtain financial reward from attorneys' fees unless they act as their own attorney, or as mentioned above, a disabled plaintiff resides in a state that provides for minimum compensation and court fees in lawsuits. Moreover, there may be a benefit to these "private attorneys general" who identify and compel the correction of illegal conditions: they may increase the number of public accommodations accessible to persons with disabilities. "Civil rights law depends heavily on private enforcement. Moreover, the inclusion of penalties and damages is the driving force that facilitates voluntary compliance with the ADA."[56] Courts have noted:

What do you want your website to look like? Consider websites that are similar to the one you’d like to build, ideally in the same industry or serving similar types of customers. Build a set of examples of types of pages, design aspects, and website features that you can hand off to the web designer — the person you hire should have experience creating websites with the features you want. If they don’t have the right skill set, they’re not the right pro for you.
People with disabilities that affect their sight, hearing, or mobility may have difficulty accessing certain parts of websites and other online properties unless certain accommodations are made. Just as businesses may need to make adjustments to their physical location so that disabled customers have easy access to the premises, companies may need to adjust certain aspects of their websites so individuals with disabilities can take full advantage of all the features and services.
Google and the government are already making asks around their expectations of accessibility as a cornerstone of website development. Google already rewards sites that check many accessibility boxes with higher rankings and the government has signaled that web accessibility standards will be required for government contractors. By building a more accessible website now, you may significantly impact your SEO and ranking potential, not to mention open the doors to possible work as a government contractor.

In 2001, for men of all working ages and women under 40, Current Population Survey data showed a sharp drop in the employment of disabled workers, leading at least two economists to attribute the cause to the Act.[52] By contrast, a study in 2003 found that while the Act may have led to short term reactions by employers, in the long term, there were either positive or neutral consequences for wages and employment.[53] In 2005 the rate of employment among disabled people increased to 45% of the population of disabled people.[54]
