Easyjet no longer use Terminal 3. They use the much nicer Terminal 2B instead.
Although at CDG, these things are relative. To a certain extent, the terminal is one thing. The "LCC" process is another point of desperation and potential for cattle-herd treatment.
But, and I stress this, you pays your money and takes your choice. What annoys me is when people choose to fly LCCs, then moan about it. If you want to be treated with more perks and finesse, then pay for it. I won't fly FR (excepting BRS-DUB, because you have to be sensible sometimes) because I value myself, my time and my dignity above a 99p fare, and I find MO'Ls attitude abhorrent. But if someone else wants to, fair enough.
