How early to arrive at airport before Vueling flights?

Both flights are considered domestic, as they are intra Schengen. 2 hours is the standard recommendation for that type of flight. However in, Granada, if you wont need to check in luggage, and will have your boarding pass, 1.5 hrs should be fine. Barcelona OTOH, is a much busier airport, so 2 hrs is prudent.

It really depends on:

--will you have checked bags? (You won't.),

--can you check in online and skip the check in counter?

--how busy is the airport. (The bigger the airport, the longer the line at security.)

If you can go straight to security on your arrival, I don't understand arriving three hours ahead of time. Unless you have lounge privilege and it's free meal time.

Thanks to you both! We'll allow more time for our flight to Porto, and give ourselves plenty of time to get through pre-boarding steps. We appreciate the assistance!

Dates? That plays a very crucial part in answering meaningfully.

Our flights are: Granada to Barcelona - May 14
Barcelona to Porto - May 19

BCN-Porto: there are several business and sports events on that day in the city, but none that big that will see people flooding the airport. Therefore, if I were you, I'd probably arrive at the airport about an hour or so before the flight -providing only carry-on luggage and that you know how to get quickly to your gate -https://barcelonainfo.site/wp-content/uploads/2017/02/bcn_terminal_1_360_wl.png if Terminal 1. Terminal 2 is smaller thus faster to reach most gates.

If you can use the app or online checkin, there's no reason to get there 2 hours early.

I flew out of Barcelona today on Vueling with a checked bag. I left my Barcelona hotel at 10:30 in a taxi and had time to spare before my flight to Sevilla.

Ekscrunchy, could you share what time you arrived at the airport and what time your flight was?
