In recent months, the difference in domestic refundable vs. non-refundable fares seems to have decreased significantly. Just today I'm booking a OW domestic First Class (Z) which is $656, and Refundable First Class (I) is only $34 more. On my last booking I noticed a similar difference (whereas I recall pre-COVID this difference was more pronounced). With all of COVID related changes, I'm assuming the main practical difference now is that a refundable fare can be returned to the method of payment, and a non-refundable fare can be cancelled only for a credit? Are there any other significant differences? For $34 I'll likely go refundable. What are others doing in this situation?
