I got a verbal commitment from a supervisor - have the name somewhere - for 25k for switching back to MCI but then got an email saying only eligible for 10k and apologizing for inconvenience and mistaken information I'll probably stay long enough to get the first 5k all at once and be looking for a better deal in the meantime. However, even though I eventually ended up with over 25k Northwest miles with Sprint they were really really really a pain to deal with!
