Do I need to find I class by searching for the entire itinerary, or can I look segment by segment? (for example, can I look at BUD-JFK separately from JFK-STT)?
I do currently have a stopover in JFK for a few days, but such a complicated itinerary seems hard for DL.com to figure out. And Google Flights is useless (it shows "no flights available" for BUD-STT using SkyTeam for most dates in Biz in August)
Is there a website you guys use for finding fare buckets availability (that isn't an expensive paid site)?
Thanks for any troubleshooting advice!
