Has anyone else done this? We did it on our recent International trip - were successful on the way there and were very happy but wasn't successful on the way back. There was space in PE so couldn't figure out how they worked this? If you are successful one way the e ticket says that the "Entire journey" is with the 2 bags not just the one leg that was upgraded but at the airport - boy do you have trouble with this and its not till you wait an hour until they get a second and third persons view do they say - yes it isn't worded very well and no you don't need to pay for the extra bag you have, when you are flying ecom home! Love to hear from anyone else...
