Flying from Miami (largest intercontinental hub near me) to anyplace in Spain in regular economy usually runs about 1,200 - 1,600 USD. But you typically must still pay for a seat selection and even to check one bag.
This year, like last week, I bought my r/t to travel to my 2020 to Camino in late April. The tickets cost me about r/t 1,000 USD in Premium Economy on Iberia. Those are the wider seats with great legroom in a smaller separate cabin from the rest of economy, where you can actually recline enough to sleep on the 8.5 hour flight over. Seat selection and 2 checked bags are included.
My routing on this trip included an "open jaw." My airports are MIA > MAD > SVA (Sevilla). Then on the return SCQ (Santiago) > MAD > MIA. Easy Peasy...
Then, a day later, I scored again, obtaining the same sort of deal, again on Iberia, but flying in peak season to volunteer for my month in July & August. Same basic routing: MIA > MAD > SCQ. The fare for Premium Economy, again in peak season, was 1,400 USD, round trip.
Yes, I know this is starting to get pricey. But an economy seat, where you must pay for a good seat and extra baggage was about 1,600. So, this is still a good deal.
I am price conscious, but I always balance the relative value. To me, these r/t fares, compared to what regular economy would have been, are only a little bit - like maybe 200 - 300 USD more. In return, I get a whole lot more comfort, convenience, and they actually treat more like a human. I have come to really like Iberia's cabin service.
As a large. stout fellow who has been traveling internationally for more than 40 years, I rate this as a good deal. As one who has sat in an economy seat for 23-hours from Washington DC to Bangkok on many occasions, trust me, this is a good deal.
The takeaway is to consider all airlines and route options. Flying TAP to Lisbon is brilliant as they connect to most larger cities in Spain as well. and BOOK EARLY, as soon as you nail your dates down.
See y'all out there...
