Aer Lingus has become notorious in recent years for constantly changing the rules on redeeming Avios - but without publicly disclosing what the rules are.
Whilst it's their currency and their rules, it would be nice if they actually told us how to play their game!
Since I was recently looking at flights between London and Ireland, I thought it would be useful to systematically look at what rules Aer Lingus has invented for each route - using a single flight to London to keep things simple.
Dublin - London
This is Aer Lingus most frequently served route with up to eleven flights a day from the Aer Lingus main base to Heathrow.
However, if you want to redeem your hard earned Avios in the next thirty days - hard luck.
But then it goes from famine to feast with 9 flights and 50 seats available for redemption on Wednesday 2nd December.
For context the Aer Lingus cash fares are also included. There are lots of days where the airline will sell you flights for less than 60 euro - but won't allow you to redeem Avios.
Cork - London
With up to four flight per day from Cork to Heathrow, this is another Aer Lingus route with a lot of seats. But the airline also operates a thirty day block on Avios redemptions on this route.
However on day 31 all four flights are available and at least 24 seats across the day.
The airline has cash fares available for as little as 70 euro in the next month - but you can't redeem your own Avios.
Ireland West Knock - London
Aer Lingus operates a single daily flight from County Mayo to Heathrow, but instead of the Dublin and Cork thirty day block, it looks something like a 12 day blackout period. And then it's only Tuesdays, Wednesdays and Saturdays for the following two weeks. Only after 20 days do we see regular Avios availability.
Whilst cash fares can be as low as 72 euro on the dark days of mid November (plus 10 euro payable at the airport), Aer Lingus seem to operate specific rules on releasing Avios seats.
Shannon - London
Aer Lingus operates three daily flights (two on Saturdays), and if you live in the Limerick catchment area you have the best opportunity to redeem your Avios. The airline seems to operate a seven day block on flights from Shannon to Heathrow.
Similar to Knock, it's Tuesdays and Wednesdays that get the most seats available. And after 30 days almost every flight is available for Avios redemption.
Cash fares in the next week are as low as 69 euro - but Aer Lingus rules mean no redemptions.
Bonus: Dublin - Birmingham
Since Aer Lingus operate a mix of two mainline A320 family aircraft and four or five Emerald ATR aircraft on this route, it's worth checking out the reward release pattern.
Whilst you cannot fly from Dublin to London on Avios in the next 30 days, you can grab a seat to Birmingham in five days time! Admittedly it's the painful 06:40 departure that is released on most days, but it's better than any other route we've seen.
There is however a 60 day block on most Emerald seats - they're not available until January.
Bonus 2: Dublin - Manchester
Since Aer Lingus operate a mix of three or four mainline A320 family aircraft and three or four Emerald ATR aircraft on this route, it's worth checking out the Manchester route.
In contrast to most of the Heathrow flights, you can fly on Avios to Manchester in a week's time - again it's mostly the painfully early 06:30 departure that is released.
There is however a 60 day block on most Emerald seats - they're not available until January.
Same day reservations
Aer Lingus does not allow same day Avios bookings. However British Airways often does have availability for same day reward travel. And BA sometimes releases extra award seats a day before travel. If you want to fly from Dublin to London tomorrow you have a choice of eight different British Airways flights - four to Heathrow and four to London City.
Conclusion
Aer Lingus have a 30 day block on Avios redemptions from Dublin and Cork to London. And a 60 day block on most Emerald flights.
The airline invents different rules for each route.
Aer Lingus needs to be honest with their customers, and publish the rules of the game.
Whilst redeeming points with most airlines is a matter of supply and demand - with Aer Lingus it's all about the rules they conjure up in HQ.
