How to book the cheapest flight to County Donegal?
With some of the most amazing flight deals around, you're guaranteed value for money with Orbitz. The following handy hints will help you land cheap flights to County Donegal — and leave you with cash to spare:

  • Consider other airports to save extra cash. Enter your preferred departure and arrival points in the form fields, then choose the 'Nearby airports' function below. It will show you any available options.
  • Similarly, click on the 'Show flexible dates' link to compare the fares on days either side of your selected departure. You may be able to pick up cheaper flight deals if your travel plans are flexible.
  • To fine tune your results, hit 'Show options.' You can search based on seating class, airlines, and nonstop and refundable flights. You can also select your preferred departure and arrival times under 'Sort & Filter' to the left.
  • The early bird catches the most impressive deals, so book your tickets the moment you know your travel dates. The cheapest airfares sell out first and prices climb as the departure date nears.
  • Combine your hotels, flights and car rental into a cost-effective package deal. Save your dollars for things that really excite you, like discovering every corner of County Donegal.
  • Flying during the busy season often means steep airfares. If possible, plan your trip outside of popular periods, such as Christmas, New Year's Eve and Easter.

What is the best time to book a flight to County Donegal?
Generally speaking, January is the cheapest month to purchase your plane ticket. This is followed by February and August. Bear this in mind while you look for a cheap flight to County Donegal.

Everyone loves saving money, so we recommend flying out earlier in the week for cheap flights to County Donegal. Orbitz data from 2020 shows you can secure the best deals on flights departing on Mondays. Tuesdays are the next cheapest day, while Saturdays are likely to cost a bundle. Many passengers tend to travel at the weekend, so leave those Saturdays for catching up with pals.

What do I need for the flight to County Donegal?
The trick to having a seamless flying experience is to plan ahead. Here are some tips to bear in mind before you depart:

  • In all cases you'll have to show proof of identification. How much? This depends on where you're jetting from. When reserving your tickets, we suggest to type in the same name, gender and birth date as listed on your government-issued ID.
  • Take a good book or a tablet crammed with your favorite movies — it'll help to while away time during your journey to County Donegal. Or if you'd rather take a snooze, a comfy eye mask will block out those bright cabin lights.
  • Long-haul trips can leave you feeling seriously cold, especially if you're flying throughout the night. If you don't want to curl up to a stranger for warmth, pack a warm layer and some wool socks.

How do I get cheap first-class/business deals to County Donegal?
Experienced travelers know how to find business or first-class airfares to County Donegal without the astronomical price tag. You can do the same with these handy tips:

  • Flexibility isn't just for the gym. Leave some room to move around your travel dates so you can snap up cheaper airfares when they crop up.
  • Search for a budget airline that offers seats in business class. They usually come with extra space and a glass of bubbly — and a nicer price.
  • Bid for an upgrade in online auctions (if available) or upgrade your seat through your loyalty program.

What is the best time to go to County Donegal?
If you want to soak up the unique vibe of County Donegal in the tourist season, February, April and May are the prime months to visit. June 20 heralds the beginning of the summer season in the Northern Hemisphere and is a fantastic time to go if you relish being outside. At this time of year, average daily temperatures normally range from 50 ºF to 60 ºF.
