We're trying to get from Krakow to London in order to fly home on Virgin this summer. AFAIK all the intra-Europe flights share the same luggage policy: 20-25kg max luggage weight per passenger, with a overweight charge of 5-12 euros per kilo and no option for a second bag. We'd like to bring an extra suitcase of personal effects.
Lacking any other reasonable options, I had the bright idea of flying EasyJet to London and just buying an extra $122 ticket so we could bring one more suitcase. But I'm not sure if that's even possible, and not sure if EasyJet is still going to hold me to the 20 kilos per person.
Would this strategy work?
What we ended up doing was flying first from Krakow to Frankfurt on Lufthansa, and then buying a completely separate ticket from Frankfurt to London (not even on the same itinerary). KraKow isn't big enough to have a lot of international options, and going to London leaves the Schengen zone. Trying to get directly from Krakow to London had too few choices. And Lufthansa has a reasonable baggage policy.
