I have seen on a few occasions that the name change will cost you some $$, however as long as you don't get some one at the checkin desk who upholds everything to the letter (pun intended), then you might be ok.
For peace of mind though, I'd try and at the very least contact them before the date of travel. I'd hate to rock up at the airport and have them deny checkin due to a speeling mustake!
