TAP airline

Hello, I'm travelling to Portugal with TAP Airlines from Romania. When trying to book the ticket online at the section 'Document Type' it says 'Passport' and I'm required the document's number.
I am travelling with my ID Card (being an EU Citizen), is it ok if I fill the document number from my ID Card, although I'm required the passport number?

An urgent reply would be extremely helpful,
Thank you

You should have the option to add another ID card type. And you should be fine traveling to PT with only that card, the passport is not necessary.

Enjoy Portugal :)

You are an EU Citizen but Romania is not part of the Schengen Area.

So according to the legislation, any citizen that enters the Schengen area from any non-Schengen Country needs to have a passport.

There is no option. It only says:
ATTENTION: Travelling to Portugal
According to the portuguese authorities, it is mandatory to collect the following personal information from passengers.
Document type
Passport

and it's asking for the Document Number.
I've tried to call the TAP Office, but no one is answering.

Thank you for your fast reply!

Thank you so much!
I also tried to book a flight through Vola (agency that sells TAP tickets), and they do not ask for a passaport when it comes to booking a ticket.
This is what I do not understand: why on the official site of TAP, when you book a ticket, they ask for the passaport and if you get the ticket through an agency, they ask only for the ID Card.

*to booking.
to book
sorry :)

mneslcl, are you certain about this ?
The information I found is that OP can travel on her Romanian ID card; no need for a passport:

That's probably because different air agreements.

For TAP any flight within Schengen area it's like a "domestic flight", outside it's considered an international flight.

mnescl this is incorrect it is within the EU http://europa.eu/youreurope/citizens/travel/entry-exit/eu-citizen/index_en.htm

richiavo, no it's not incorrect. You must read that link more carefully.

Romania is still not a border-free country within the EU.

So Romanian airports are considered "external flights".

Even if you don't need to have a passport if you have an ID card, it's advisable to have one because national rules may change from one country to the other within Schengen.

Just because there's a minimum check for any tourist , that doesn't mean in certain cases there would be a larger check to a citizen of the same nationality.

mneslcl, your posts are simply misleading. Any EU citizen has a right to travel everywhere in the EU with just his or her national ID card, no need for passport. This applies regardless of the country in question being in the Schengen area or not.
The Schengen area is about border controls, not passports. A EU citizen travelling between the Schengen area and a Member State not belonging to the Schengen area (e.g. France to the UK or Romania to Portugal) will be subject to immigration check at the border but he or she is legally entitled to cross the border with just his national ID card.

I'm with meczko on this one. I frequently travel from Schengen to the UK with just my Belgian id card, no problem. Maybe I'll give TAP a call tomorrow, I'm kind of intrigued.

mnescl it is you who needs to read it more carefully it clearly state that those countries that are not Schengen you require a valid passport or id card. For travelling between Schengen countries you technically do not require a passport or id card.

Richiavo, it is not true either. Technically, you still need to hold valid proof of identification (either passport or ID card) when travelling across a state border even inside the Schengen area. The difference is that inside the Schengen area it is not checked at the border but spot checks inside Member States are possible.
To sum it up - a national ID card of a EU Member State or a passport are required to cross borders between EU Member States, with ID card being perfectly enough. This applies regardless whether you travel inside or outside the Schengen area. The only difference is that there are no immigration checks at the actual border inside the Schengen area, while those checks are still done on the border of Member States which do not belong to Schengen area (UK, Ireland, Romania, Bulgaria, Cyprus, Croatia).

The rules at the borders aren't followed strictly, as I experienced. I used to fly often from Sweden to the UK and Portugal. For flights to the UK I had to get through Swedish passport control and show my passport, before departure. The gates to non-Schengen countries are in a separate area of the airport.
On arrival in the UK (country outside Schengen), I showed either my Swedish ID or driving license, and I was getting through without problems. Afaik, driving license shouldn't be accepted as an ID at border check, but it was. Similarly in Portugal, although that is much easier when flying between two Schengen countries, where there's no border check.

Fieldgate, even if Swedish immigration officers ask for passport, you can still insist on flying to the UK only with your Swedish ID. That's your legal right and Swedish immigration officers are certainly qualified enough to know it. Obviously sometimes it is easier just to show the passport than to explain the thing.
A driving licence is formally not the right identification for cross-border travel within the EU but there is apparently also some discretion for UK immigration officers. If on seeing you driving licence they are reasonably convinced that you are an EU national, why not let you in?

By the way, in Portugal on many occasions I was asked for passport or had to fill in questionnaires with a "passport number" field. On hotel check-in, opening a banking account, getting a tax identification number etc. It was always perfectly acceptable to show my Polish ID instead of passport. Sometimes I needed only to explain its content, as there are not so many Polish speakers in Portugal :)
It seems that asking for "passport" is in many cases just a left-over from pre-Schengen times. Anyway, it is already generally known that a EU citizen from another member state does not need to have it.

You should have just entered your ID card number where it says passport. When asked for it at the airport, show your ID with the number.

This is Portugal, nobody is going to make a special "ID card number" field for you.
