Sooooo My spouse is leaving a Delta Connection airline for mainline US Air.
What are the major differences in flight benefits?
- I already know of having to pay $20 upgrade for domestic first class
- and $100 for International upgrades and you have to purchase a coupon on advance
- US Air does not fly to SE Asia (American does but there is no buyout yet)
- What other ailines are free flights available
- Anything to add :)
