Emirates is also introducing a curated selection of eco-conscious products, including upcycled travel pouches and document holders, reflecting the airline’s commitment to sustainability. Guests are welcomed with freshly brewed coffee, reinforcing Emirates’ hallmark hospitality on the ground.

The grand opening was attended by Emirates’ Deputy President and Chief Commercial Officer, Adnan Kazim, alongside representatives from the UAE Embassy and Changi Airport Group, underscoring the strategic importance of Singapore as a hub for Emirates in Southeast Asia. In 2024 alone, Emirates carried over 800,000 passengers between Singapore and Dubai, operating four daily flights to Dubai and beyond, plus a daily service to Phnom Penh.

This store is the first of more than 40 planned worldwide as part of a S$35 million investment, positioning Emirates as a leader in premium, high-touch retail experiences that blend technology, personalization, and luxury. The new Emirates World store is set to redefine how travelers engage with the airline, offering a seamless, informative, and immersive space that brings the ‘Fly Better’ promise to life both in the air and on the ground.

Strategic Implications and Explanation

The Emirates World store is more than just a physical sales channel; it is a strategic move to deepen engagement with high-value travelers in a digital age. By combining personal service, interactive technology, and exclusive experiences, Emirates aims to differentiate itself in a competitive market and collect valuable customer insights for tailoring future offerings.

The investment in physical retail, alongside digital integration, allows Emirates to create a consistent and elevated brand experience across all touchpoints, ensuring that travelers receive the same level of care and luxury whether they are booking online or in person.

This initiative also positions Emirates to capitalize on the growing demand for experiential retail, where customers value face-to-face interactions and immersive experiences, especially when planning significant journeys. The store’s success could influence the broader travel industry, encouraging a renewed focus on high-touch, personalized customer service in the premium segment.

Qatar Airways is widely regarded as one of the world’s leading luxury airlines, known not only for its exceptional service and modern fleet but also for the exceptionally high standards it demands from its cabin crew. Behind the airline’s polished image lies a comprehensive set of strict rules and regulations that govern every aspect of cabin crew members’ professional appearance, behavior, and lifestyle.

These rigorous policies, some of the most stringent in the aviation industry, are designed to maintain the airline’s prestigious reputation and ensure a consistently flawless experience for passengers around the globe.

Strict Grooming and Appearance Guidelines

Qatar Airways enforces highly detailed grooming standards to uphold its reputation as a premium airline. Female cabin crew are required to wear full-coverage foundation and concealer, matte blush without shimmer, and lipstick or nail polish in specific shades such as deep pink, red, or burgundy to align with the company’s brand image.

Skincare is emphasized, with crew trained to use long-lasting, durable makeup products to maintain a flawless look during long-haul flights. Male crew members must be clean-shaven, with neatly trimmed mustaches above the lip line; beards and visible gray hair are prohibited, and bald spots must be concealed.

Hair Styling Requirements

Female crew members must style their hair in low buns secured with hairnets and scrunchies, and only natural hair colors are permitted. Male crew are expected to maintain a neat hairstyle using grooming products like wax or clay, avoiding any greasy or overly styled looks.

Uniform Regulations

The airline maintains strict uniform policies:

• Crew must carry spare uniforms on every flight to address any unexpected incidents.

• Jewelry is limited to simple stud earrings and wedding rings with embedded stones for safety reasons; men are generally limited to wearing watches.

• Female crew must wear matte, skin-tone-matched stockings.

• Only mild fragrances are allowed to prevent discomfort to passengers.

Lifestyle and Conduct Rules

• Crew members live in company-provided accommodation monitored by electronic keycards and subject to unannounced checks.

• The pre-flight curfew has recently been shortened from 12 to 9 hours, with a 90-minute allowance for leaving the accommodation during this time.

• Sharing photos in uniform or depicting alcohol or cigarettes on social media is strictly forbidden.

• Visitors of the opposite sex were traditionally restricted to visiting hours between 7 a.m. and 10 p.m., with mandatory registration.

• Alcohol, tobacco, and pork products are banned in crew living quarters.

Recent Policy Adjustments

Qatar Airways has relaxed certain rules in recent times:

• Overnight curfews on days off have been lifted, allowing greater personal freedom.

• Pregnant cabin crew can now transition to ground-based roles instead of being forced to resign.

• The requirement to obtain CEO approval for marriage after five years of service has been simplified.

Recruitment and Benefits

The airline is highly selective, accepting only about 6–8% of applicants. Candidates must meet physical requirements such as a minimum arm reach of 212 cm, be fluent in English, and relocate to Doha. Benefits include company-provided housing, international medical insurance, and discounted travel opportunities worldwide.

Operational Procedures

During flights, crew adjust their uniforms according to service phases: wearing blazers during boarding and switching to blue “dining jackets” during meal service. Female crew carry secure handbags containing makeup kits and manuals, all protected by passcodes.

Cultural Distinctions

Unlike many Western airlines that have relaxed uniform and grooming policies, Qatar Airways maintains traditional, highly polished standards to reinforce its five-star luxury image. Every detail, from nail polish color to sock styles, is carefully regulated to ensure a consistent and upscale passenger experience.

Compensation and Discipline

Starting salaries for new cabin crew are approximately QR 3,300 (around $900), rising to QR 3,750 after six months, with additional hourly allowances for flight time. The airline enforces strict discipline: arriving even five minutes late to accommodation curfews can lead to warnings, and repeated infractions may result in termination.

Training and Compliance Checks

New recruits receive intensive training led by grooming officers, covering makeup application, hairstyling, and uniform standards. Pre-flight inspections ensure all crew meet the airline’s exacting appearance and conduct requirements.

By balancing these rigorous standards with recent reforms, Qatar Airways continues to ensure its cabin crew embody the elegance, professionalism, and precision that define its global reputation as a leader in luxury air travel.

Dubai Airports has set a new global standard for accessible travel by rolling out a comprehensive suite of autism-friendly services and training initiatives across Dubai International (DXB) and Dubai World Central (DWC). As the world’s first international airport to receive the Certified Autism Centre™ (CAC) designation from the International Board of Credentialing and Continuing Education Standards (IBCCES), DXB has embedded autism-inclusive practices at every level of the passenger journey.

A cornerstone of these efforts is the launch of the Assisted Travel Lounge at Terminal 2, a pioneering facility designed to offer a calm, sensory-friendly environment for People of Determination (POD), including travelers with autism and hidden disabilities. This lounge, developed in partnership with dnata, is part of a multi-million-dirham program that will expand to other terminals, providing specialized assistance, quiet zones, and dedicated support for families.

Dubai Airports has also prioritized human connection by equipping 45,000 employees—including frontline staff, airport partners, customs officials, and airline personnel—with IBCCES-accredited autism awareness and sensory sensitivity training.

This training, which has increased by 36% year-on-year, ensures that staff can recognize and appropriately respond to the needs of neurodiverse travelers, reducing anxiety and fostering a supportive environment throughout the airport. Guest Experience Ambassadors, easily identified by Sunflower pins, are stationed at key touchpoints to offer informed assistance to those with hidden disabilities.

To further streamline the travel experience, Dubai Airports offers a range of practical services: complimentary two-hour parking, dedicated taxis, wheelchair support, and priority lanes for Sunflower Lanyard holders. The DXB Travel Planner, an online visual guide, helps families prepare for their journey, while the airport’s Autism Friendly Route ensures a smoother passage through check-in, passport control, and security.

These initiatives are part of Dubai’s broader ambition to become a Certified Autism Destination™ (CAD), supported by the Department of Economy and Tourism. The airport’s efforts have led to increased guest satisfaction, positive feedback from the autism community, and international recognition, including the Airports Council International (ACI) Accessibility Enhancement Accreditation.

Through its “We All Meet the World Differently” campaign and ongoing collaboration with local and international advocacy groups, Dubai Airports continues to champion neurodiversity, ensuring that every traveler—regardless of ability—feels welcomed, respected, and supported from arrival to departure.
