Etihad Airways is doubling capacity from Manchester airport and a string of other European destinations.
The northwest hub will gain year-round double-daily flights to Abu Dhabi from December, up from seven flights a week.
The same frequency is also being offered from Paris, Milan, Rome, Frankfurt, Munich, Zurich, Barcelona and Madrid.
The new European flights are timed for morning and evening departures and arrivals, offering travellers the flexibility to choose the schedule that suits them, according to the UAE carrier.
Meanwhile, service to Bali from the airline’s Abu Dhabi hub is being upgraded to daily from April 2025 after “massive” customer demand.
Chief revenue and commercial officer Arik De said: “We are delivering on our strategic promise to serve more key destinations twice daily as fast as we can, and our summer schedule underscores our commitment to growth and further supporting tourism in Abu Dhabi.
“By aligning our schedule to offer 2pm departures from Abu Dhabi, we provide guests with convenient check-out times from their hotels, allowing them to make the most of their stay in our beautiful city.
“Morning arrivals offer tourists the benefit of early hotel check-ins and extra time to explore the city’s attractions, and evening arrivals are ideal for those who prefer a seamless transition after work or other commitments.
“For business travellers, the schedules accommodate full working days at both the beginning and end of their trip.
“We’re excited to add Warsaw and Prague to our network, and travellers can look forward to more route announcements very soon.”
