IF you choose a voucher

BE CAREFUL as my Aer Lingus voucher states it is only valid for 5 years from the date of issue

Only valid in the currency of the original flights booked

AND
CANNOT be used for any partner airlines or segments OR Codeshares

SO I can only book direct flights with AL to destinations inc USA or Europe.
IF the aircraft is not operated by AL, my voucher can't be used?

SO applying the same rule in the UK, if you booked in sterling, your voucher is only valid for flights from the UK
PLUS, if you go 'indirect', the voucher WONT be accepted for any flight NOT OPERATED BY AER LINGUS ie NO CODESHARE


Maybe their rules are different for the UK. You need to check carefully before committing to a voucher.

You have to go direct with AL
