evidence: Even when travelers prepare their journey at home, they can easily know what type of assistance the airport provides since airports all have a dedicated page on assistance service on their website. Plus all airport websites have to be accessible to enable visually impaired people to easily get the necessary information. Such is the case with Denver International Airport (DEN) that lists all its accessibility services and details specific subjects (the location of its accessible parking spaces for example). A map of the airport and its terminals is available on the website but also on the airport app. Smartphones are indeed a vital tool for people with disabilities enabling them to gain more autonomy. [...] Easily accessing check-in counters and boarding gates makes our experience better. For travelers in wheelchairs, that means lowered counters, wide-access doors and security lanes. For them and other travelers with a lot of luggage, all airports have elevators, escalators and ramps. With wide ramps, one of the principles of universal design, people can easily and rapidly move around in the airport. Embracing universal design, airports create a better and more accessible environment to facilitate the trip of all their passengers. The restroom stalls of Minneapolis-Saint Paul International Airport (MSP) have doors that swing out and side grab rails. Plus some space for those who have a carry-on suitcase.
