Got it - thanks. How expensive does the flight need to be relative to the trip credit when looking at the base fare vs. total price including taxes + fees? For example, if I had a trip credit of $90 would the example flight below work (base fare of $75 and $20 of fees = $95 total) or do I need a flight with a base fare of $90?
