Hello again folks, I have another question for you all if you don't mind. If I'm being a pesky rev pax with all these posts, please please PLEASE let me know. I'd rather be comfortable here than have some questions answered (if even that happens).

I'm about halfway though my semester here, and am thinking of my journey home. One part that I've thought about is the checked bag fees that I'm bound to have... I'll have 2 of them, and paying online at United may not be an option (I won't have computer access 24 hours or less before departure). However, I just thought of something earlier today. First off, a reminder: I have 2 tickets for my flights. On my way home, I'll be flying IB SVQ-MAD-LHR and BA LHR-ORD on one ticket, and then UA ORD-MSP on another. I did the same thing on my way here, but in reverse order (and LHR-MAD was a BA flight, but that's just a little detail).

Anyway, I was thinking about how the CSA for United offered to check my bags all the way to Seville when I mentioned what I was doing. I declined for a couple reasons, but now I'm thinking: What if I asked about checking my bags from Seville all the way to Minneapolis? Iberia won't charge me for the checked bags on my ticket, and in theory I should be able to just throw them back on the belt after going through customs at ORD, with that MSP sticker already attached. Bag sorters see a sticker saying MSP on it, with my flight number, and load it up. I then check in to get a boarding pass from United, and say I have no more bags to check (that's the one part I'm a little nervous about, but I don't think they check for payment at every scan, and what are they going to do? Hold my bags hostage).

Obviously, there's probably a better chance of my bags getting misplaced, but if I'm home I can stand a delay of a couple days.

I now ask you guys to tell me why my plan won't work, por favor
