How much does a taxi from the La Guardia airport cost to the Pennsylvania hotel ???

You have a free bus that takes you to the Astoria station and from there you take the subway

OMG, how expensive, thank you very much for your help, we will do so.

Taxis charge about $ 60 not including fares and checkpoints. LYFT and UBER are better close to $ 52 with the same terms. Much cheaper to take Port Authority red buses or MTA buses and A, C or E train to 34th Street and 8th Avenue.
