It's now 2023, so 7 years further and after corona. Did anything change since this question was answered???

I just bought a ticket on Vueling and I received an email with the tickets, saying "Remember that you are travelling with ONE UNDERSEAT BAG ONLY."

Now I think this is just a 'standard email' that everybody gets, whether you bought a 'normal' full price ticket or you bought a nonrev (ISA) ticket... But I would like to make sure. Thing is: we are only going for a weekend and don't want to check in a suitcase, only taking hand luggage, so I really need the option of the 10 kg max "overhead luggage"...

Thanks in advance!!!
