I was able to price this out over phone earlier today but out of EWR for $980. Which doesn't really work for me since I'm at SJO, and could easily buy a cheapo ticket to IAH with Spirit.
Any other ideas? I can price it out on the UA site by multi-city, and it's all good until the GUM-MNL-IAH flight which takes it up to $2900. IAH-HNL-GUM(Via UAL154) comes in at around $400 before adding MNL-IAH
