Has anyone done this before? When you apply for a visa you show one ticket but fly on a different one. Is that okay or could it cause problems?
The itinerary for the consulate must show departures from Russia and returns to Russia — that’s a requirement for the application documents, not for how you actually travel. A visa grants the right to visit the Schengen area, but it doesn’t oblige you to take the exact flight you showed. The only important thing, if it’s a multiple-entry visa, is that the first entry and exit should preferably be into and out of the country that issued it.
There was a round‑trip itinerary to Russia; I requested the Italian one. Thanks, that’s clearer now. And later, when I apply for the extension, won’t they question that I flew on different flights than the ones I showed?
The biggest problem with an extension is proving that you used the visa the way you claimed. Did you apply for an Italian one? Under Schengen rules, a visa must be applied for in the country where you’ll spend the most days on your first trip — and they check exactly that at your next application.
I received a Spanish Schengen visa and want to enter through Italy — the visa manager says that if I don’t enter Spain, next time they’ll refuse. I will spend more days in Italy, so formally I should have applied through the Italian consulate in the first place. So I’m wondering: can I apply through Italy next time, or will they also refuse because there won’t be a Spanish entry stamp?
Entering Italy for the first time via other countries is possible — I know, for example, that you can travel that way; some people drove through several countries by car and everything went fine. If your next trip is mainly to Italy, apply through the Italian consulate and submit everything correctly — the passport stamps will show where you actually were. The absence of a Spanish entry stamp isn’t a problem if you spent fewer days in Spain.
When reapplying, they check the entry stamps, not the booking from the first application.
