United Airlines is offering double award miles for travel between Washington DC and Dublin or Manchester. Keep in mind this does not mean double PQM or Premier Qualifying Miles.

The Manchester bonus miles promo runs from May 1 to September 30 and requires you to register for the promo which can be done from within your MileagePlus account.

The Dublin bonus miles promo runs from June 7 to September 30 and also require you to register in order to be eligible.

There are no limits as to how many miles can be earned with this promo!!

There are some minor terms and conditions that you need to be aware so please read through them carefully to make sure you qualify! I’d post them here, but my IPad is challenging my cut and paste skills today……

EDIT: Now that I’m home, I can add the T/C’s:
