Aer Lingus redemptions are still far cheaper when booked at avios.com (but no 2-4-1’s)

It’s been a while since we talked about booking Aer Lingus flight redemptions, but a big release of business class reward seats between Dublin and Philadelphia this week (hat-tip to US site Frequent Miler) reminded me to remind you of how you can pay too much.
If you were thinking of visiting Philadelphia next spring, there are two business class seats per flight available virtually every day between January and March on Aer Lingus from Dublin.
I’m not here to recommend Philadelphia in January or not – I’m guessing it could be chilly – but late March / potentially April if the seats are there should be better. I simply want to use it as an example.

If you were planning on booking Aer Lingus in business class, here is my review of Aer Lingus A321LR business class. Here is Rhys reviewing one of the A330 Aer Lingus business class routes from Manchester.
There are two ways of booking Aer Lingus redemption flights
Aer Lingus flights are now bookable on ba.com so this is where you would logically decide to start.
If you want to use a British Airways American Express 2-4-1 voucher on Aer Lingus (which you now can, plus Iberia), you MUST book on ba.com.
You’ll get a bad deal, but you’ve got no choice!
This isn’t where Aer Lingus frequent flyers book their redemptions though. They use the avios.com website, which is also used by Vueling Club members.
You can’t just go to avios.com and log in with your British Airways Executive Club account details. You need to open an Aer Lingus Aer Club or Vueling Club account (free, on their respective websites) and then use ‘Combine My Avios’ on avios.com to move your points across from British Airways Executive Club.
Moving Avios is free, instant and can be reversed if needed.
A full HfP article on using ‘Combine My Avios’ is here.
Look at how ba.com rips you off when booking Aer Lingus flights
I did dummy bookings for business class flights using Avios between Dublin and Philadelphia. By starting in Dublin and not London you can avoid long haul UK Air Passenger Duty, albeit that you need to buy a ticket to Dublin.
Using ba.com:
- Dublin to Philadelphia, return in Business: 100,000 Avios + £419
- Dublin to Philadelphia, one way in Business: 50,000 Avios + £221
- Philadelphia to Dublin, one way in Business: 50,000 Avios + £691

If we swap over to the avios.com website to book exactly the same flights:
Using avios.com:
- Dublin to Philadelphia, return in Business: 100,000 Avios + £241 (save £178)
- Dublin to Philadelphia, one way in Business: 50,000 Avios + £132 (save £89)
- Philadelphia to Dublin, one way in Business: 50,000 Avios + £108 (save £583!)
The savings in taxes and charges are huge. A couple flying from Dublin to Philadelphia and back in business class would save £356 in charges by booking at avios.com.
The really scary saving is the one you get if booking a one way flight from Philadelphia to Dublin. The £691 taxes and charges bill drops to £108 if you use the avios.com website.
Even avios.com is a bit of a swizz though ….
United Airlines is, intriguingly, an Aer Lingus partner. This is despite the fact that United Airlines is in Star Alliance and Aer Lingus, whilst not in an alliance, has a parent aligned with oneworld.
Let’s look at what it would cost to book using United Airlines miles using Philadelphia to Dublin, one way, in Business.
The same flight which costs 50,000 Avios + £691 via ba.com, and 50,000 Avios + £108 via avios.com, costs just 88,000 United MileagePlus miles + $5. Avios.com is still pocketing over £100 of random charges.
