lhr-sjo
I'm new to this. I've only redeemed airmiles before on BA and Virgin (through their frequent flyer schemes) and both are very straightforward.
Ideally I'd like not to have go via continental Europe (or anywhere for that matter where blizzards are likely in January - hence Houston) and get to SJO with just one stop - via canada is fine, but I don't know how to go about checking this out. I'm finding *A ICC quite unhelpful. I've got the ANA tool but as I said it's a bit early to check out the dates.
I only looked at CO because they have a routing LHR-Newark or Houston-SJO.
Any other suggestions would be greatly welcomed. Thanks
