Recently purchased two OW TUS-HNL UA First Class for June. United changed equip to wide body: bigger plane = more first class seats = dropped prices. The difference is about $300 per ticket. Do I:
1) Call to beg to get a refund credit and are there any processing fees (used to be $50, sometimes waived)
2) Is this a strategy?: Change itinerary to a different date and then a few minutes later, change again, back to the date I want, at the lower rate? (Will United's computers know what I have done?)
Thanks I'm a UA newbie.
