Award flight changed
I just got notice of award flight changed bna-clt-lhr and now we have 8 hr layover in LHR and won’t arrive KRK until 6:45 pm so we lose most of day in KRK. .
Flight is not until July. No options available to get us there earlier. There is a flight leaving previous day without long layover.
Should I try getting through to airline to ask for change? With storm causing flight disruptions right now should I wait to call? How long do I have after flight change to ask for new flight?
Advice on this situation please and thank you.
