Here's some slightly rounded examples from me in case it helps anyone else.
- I have *two* itineraries, combined travel credit is about $160
- I got one offer to exchange that for 50,000 Frontier miles
- Plus, I still have the additional 3x$50 travel credit to use before End of Year
- My wife has one itinerary, travel credit is about $300
- Got the offer to exchange it for 70,000 Frontier miles
- Plus, she still has 4x$50 travel credit to use by end of year.
