As someone traveling from Spain to the United States for the first time, I was quite overwhelmed by the paperwork, visa requirements, and unfamiliar travel rules. I reached out to the Allegiant Air Spain Office for advice, and the staff were incredibly helpful. They explained the importance of the ESTA visa waiver, advised on necessary documentation, and gave me detailed information about what to expect when flying with Allegiant Air domestically in the U.S. They also informed me about Allegiant’s low-cost model, emphasizing that meals and checked bags are not included by default, so I could budget accordingly. What I appreciated most was their patience; they answered all my questions clearly and didn’t rush me. Because Allegiant doesn’t fly directly from Spain, the office helped me understand how to coordinate connecting flights via other airlines. Thanks to their support, I felt confident throughout the booking and travel process. I’d recommend anyone flying Allegiant from Europe to contact the Spain Office first—it’s a valuable resource for international travelers unfamiliar with the airline.
