Well, via this link we now have full details of what has been rumoured for a few days that tickets issued by travel agents, most importantly corporate buy used rental car travel agents, will be upgradable with Avios points.
There is quite a bit of confusion about this topic, in particular what the effect will be on standard Miles for Upgrade transactions. buy used rental car I will try to separate out the facts and the considered speculation from the hype.
For the first time, tickets booked buy used rental car via a corporate or standard travel agent can be upgraded with Avios to the next class of travel.  BA has allowed tickets booked on ba.com to be upgraded with Avios for some years, via a process known as MFU ( miles for upgrade ).  The key MFU rules will also apply to upgraded corporate tickets:
The cost of the upgrade is the difference between a one-way redemption between the two classes (ie First Class one-way to New York is 60,000 Avios, Club World is 40,000, therefore buy used rental car the upgrade buy used rental car from Club World to First costs 20,000 Avios)
Once you have processed the upgrade, your corporate travel buy used rental car agent loses all control of your ticket and can no longer make any changes to it.  If you need to change your plane home, you can no longer ring your corporate travel agent you will need to ring BA.
So, what is the net result buy used rental car of all this?   Will it mean, as some online buy used rental car commentators have suggested, the end of upgrade availability for the general public?  My personal view is no , and I think I will personally benefit from this change.  Let s look at some facts.
Most personal reward flights are booked months in advance.  Most corporate flights are booked a few days in advance.  You are not therefore competing for the same reward availability.  Corporate upgraders are taking availability from flights that BA opens up for Avios redemptions at the last minute when did you last book a family holiday at 3 days notice?
Flyers will need to use their personal Avios to do this.  Some may prefer to keep back their Avios to travel with their family, buy used rental car rather than use them on a work trip.  And if they are using them for short notice upgrades, then there will be fewer people with enough Avios to be fighting you for those Summer tickets to Florida.
More importantly, a lot of business travellers will not be willing to pay the extra taxes, which will be coming out of their own pocket.  On Heathrow to New York, for example, the tax on a World Traveller Plus return is £414.  The tax on a Club World return is £520.
All in all, I am not too worried.  I don t think there will be fewer Avios seats when I book my family holidays six months in advance.  I will also, given our huge Avios points haul between me and my wife, be able to upgrade her on business trips without it making any real dent in our balance.
Whilst I don t want to scaremonger, this does not seem like great news.  BA could, for example, withdraw the ability to upgrade cheap, non-refundable buy used rental car Club World and World Traveller Plus tickets it is already impossible to upgrade such tickets using points from BA s On Business programme.  Let s wait and see.
However, what I was really trying to raise as a thought was that now BA will have some routes (although officially unannounced when I wrote that yesterday) which just have WT and CW, if they do allow upgrades on thouse routes you will have a situation where you can upgrade from WT to CW on some routes but not on others. Which is less than ideal. [Even more so if any of the routes end up being mixed between 3/4 class and 2 class services.]
[It will also mean that both AA and IB will allow Economy to Business upgrades, but BA won't. Yes, they fly different portfolios of cabins, but it will still be odd, a Y ticket can be taken to a bed on AA+IB, and now on some BA routes, but not others. As such, could BA be going to allow WT to CW on all routes? - It is restricted to Y,B,H as the underlying.]
