| Basis of Presentation and Use of Estimates                | (a)  Basis of Presentation and Use of Estimates:Frontier Communications Corporation and its subsidiaries are referred to as "we," "us," "our," "Frontier," or the "Company" in this report. Our interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2011. Certain reclassifications of balances previously reported have been made to conform to the current presentation. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary, in the opinion of Frontier's management, to present fairly the results for the interim periods shown.  Revenues, net income and cash flows for any interim periods are not necessarily indicative of results that may be expected for the full year. For our interim financial statements as of and for the period ended March 31, 2012, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this quarterly report on Form 10-Q with the Securities and Exchange Commission (SEC).The preparation of our interim financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities at the date of the financial statements, (ii) the disclosure of contingent assets and liabilities, and (iii) the reported amounts of revenue and expenses during the reporting period.  Actual results may differ from those estimates.  Estimates and judgments are used when accounting for allowance for doubtful accounts, impairment of long-lived assets, intangible assets, depreciation and amortization, income taxes, purchase price allocations, contingencies, and pension and other postretirement benefits, among others. Certain information and footnote disclosures have been excluded and/or condensed pursuant to SEC rules and regulations. |
| Revenue Recognition                                       | (b)  Revenue Recognition:Revenue is recognized when services are provided or when products are delivered to customers.  Revenue that is billed in advance includes: monthly recurring network access services, special access services and monthly recurring local line and unlimited fixed long distance bundle charges.  The unearned portion of these fees is initially deferred as a component of other liabilities on our consolidated balance sheet and recognized as revenue over the period that the services are provided.  Revenue that is billed in arrears includes: non-recurring network access services, switched access services, non-recurring local services and long-distance services.  The earned but unbilled portion of these fees is recognized as revenue in our consolidated statements of operations and accrued in accounts receivable in the period that the services are provided.  Excise taxes are recognized as a liability when billed.  Installation fees and their related direct and incremental costs are initially deferred and recognized as revenue and expense over the average term of a customer relationship.  We recognize as current period expense the portion of installation costs that exceeds installation fee revenue.As required by law, the Company collects various taxes from its customers and subsequently remits these taxes to governmental authorities. Substantially all of these taxes are recorded through the consolidated balance sheet and presented on a net basis in our consolidated statements of operations.  We also collect Universal Service Fund (USF) surcharges from customers (primarily federal USF) that we have recorded on a gross basis in our consolidated statements of operations and included in revenue and other operating expenses at $29.7 million and $28.1 million, for the three months ended March 31, 2012 and 2011, respectively.                                                                                                                                                                                                                                                                                                                                                             |
| Goodwill and Other Intangibles                            | (c)  Goodwill and Other Intangibles:Intangibles represent the excess of purchase price over the fair value of identifiable tangible net assets acquired. We undertake studies to determine the fair values of assets and liabilities acquired and allocate purchase prices to assets and liabilities, including property, plant and equipment, goodwill and other identifiable intangibles.  We annually (during the fourth quarter) or more frequently, if appropriate, examine the carrying value of our goodwill and trade name to determine whether there are any impairment losses.  We test for goodwill impairment at the "operating segment" level, as that term is defined in U.S. GAAP.  Our operating segments consist of the following regions: Central, Midwest, National, Northeast, Southeast and West.  Our operating segments are aggregated into one reportable segment. The Company amortizes finite lived intangible assets over their estimated useful lives and reviews such intangible assets at least annually to assess whether any potential impairment exists and whether factors exist that would necessitate a change in useful life and a different amortization period.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |

| - Definition
Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
