Question about UA travel waivers. 1K on a UA metal flight to Europe, but LH ticket stock (in this case, Economy Light).
a) Does UA's travel waiver apply in this situation or does LH need to also have a waiver?
b) If UA's waiver applies, do I call UA or LH?
c) Will the Economy Light be a problem for switching routing to a UA itinerary via IAD/EWR? Or would they only switch me to a LH metal flight?
