For example, say I have a connection in PHX and I'd like a longer layover because a friend wants to meet me at the airport for lunch. Can I take an earlier flight to PHX but keep my original connecting flight? Is it a problem if the new connection time exceeds 4 hours (the usual limit for connection times)?
