The amount of Avios needed (currency of Aer Lingus credit card rewards) depends on several factors, like the cost of the ticket, the distance, class of the flight and other. What is more, fees may be added to the cost of the award ticket. So there is no direct answer if 50,000 Avios is enough for your flight or not. You should keep in mind that there may be some restrictions and limitations when redeeming for award flight.
If you want to get a travel credit card to earn miles for a flight, consider general travel rewards credit cards. These cards often come with good rewards and generous sign-up bonuses. For example, consider the Discover it® Miles credit card. With this card you will earn unlimited 1.5 miles on all purchases. All the miles that you've earned are matched at the end of the year (provided you are a new cardmember). So if you earn 35,000 miles, you get 70,000 miles. That’s $700 towards travel! This card doesn't have annual and foreign transaction fees.
