Can someone please reality check this for me? I got so inspired by this board that I think I just figured out a way to get my travel party to Barcelona and still have the card companies giving *us* money...
Party of 6 with 4 adults (all with excellent credit) and 2 kids
United has a nonstop from Newark to Barcelona and asks 30k miles+ $6 for the one way (we're taking the WBTA so we only need one way)
United's MileagePlus Visa is currently offering 30k and a $100 sign-up bonus after $1,000 spent: each adult can get this card and get a free trip to Barcelona with $94 left over
For the children's fares, I just applied for the Chase Sapphire: 50k miles sign up (after $4,000 spent) + 5k miles with co-cardholder's first purchase. So, when as soon as I spend $5,000 I should have a total of 60k miles for the children's fares.
Both cards are first year with no annual fee... so, as I see it, as long as my parents spend $2,000 on their cards and DH and I spend $7,000 (ie. paying for EVERYTHING and our vacation for 3 months), we will walk away with 6 tickets to Barcelona and $364 in statement credits. And, yes, we're pay-in-full monthly sorts of folks.
What am I missing? It almost seems to good to be true.
